The examples of polar localization given here are from a variety of bacterial species and concern a disparate array of cellular functions. I conduct both basic and translational research on cyclin-dependent kinase inhibitors. We demonstrate that SciP binds to DNA at a motif distinct from the CtrA binding motif that is present in the promoters of genes co-regulated by SciP and CtrA. Three global regulatory proteins cycle out of phase with one another and drive cell cycle progression by directly controlling the expression of 200 cell-cycle-regulated genes. In contrast to Escherichia coli, the Caulobacter Tol-Pal complex is essential. Contreras, I., Bender, R. A., MANSOUR, J., Henry, S., Shapiro, L. In situ immunoassays for translation products. Epistasis experiments placed fliX within class II of the flagellar regulatory hierarchy, suggesting that FliX functions at an early stage in flagellar assembly. These changes in DNA methylation could signal differential binding of regulatory proteins to activate or repress transcription. Using cluster analysis of the resulting set of 12-element vectors for each of these strains, we identified 52 strains with mutations that affected the localization pattern of the three tagged proteins.

Current: Clinical Variant Scientist, ARUP Laboratories. The polar organizing protein Z (PopZ) localizes to the polar regions of C. crescentus where it is known to form a distinct microdomain. Further, we find that overexpression of the bridge protein SpmX in Caulobacter disrupts this ordered assembly, generating ectopic cell poles containing both PopZ and DivJ. The transition of a swarmer cell, with a single polar flagellum, into a sessile stalked cell includes several morphogenetic events. Ph.D. 1972 Purdue University The pilus assembly protein TadZ (called CpaE in Caulobacter crescentus) is ubiquitous in tad loci, but is absent in other type IV pilus biogenesis systems. Daniel E. Ho is the William Benjamin Scott and Luna M. Scott Professor of Law at Stanford Law School, Professor of Political Science, Senior Fellow at the Stanford Institute for Economic Policy Research, Associate Director of the Stanford Institute for Human-Centered Artificial Intelligence, and Director of the Regulation, Evaluation, and Governance Lab (RegLab). Here, we show that ATP depletion promotes phase separation in bacterial condensates composed of intrinsically disordered proteins. 2014;47 (11): 2709-2714, CLINICAL ORTHOPAEDICS AND RELATED RESEARCH -Ladd, A. L.2014;472 (6): 1681-1684, Clinical orthopaedics and related research -Ladd, A. L.2014;472 (4): 1093-1094, CLINICAL ORTHOPAEDICS AND RELATED RESEARCH -Halilaj, E., Rainbow, M. J., Got, C., Schwartz, J. In addition, transcription of phiCdl DNA by the E. coli enzyme produced a subset of transcripts not synthesized by the C. crescentus enzyme. The homologous sequence between IS2 and 16S rTNA is the same sequence in phi X174 DNA which codes for the ends of the E and D gene and the start of J. Many important biological processes occur deep inside living organisms. The mutant lacks a flagellum and pili, and may have an abnormal DNA phage receptor site. Faithful chromosome segregation is an essential component of cell division in all organisms. The Caulobacter life cycle, defined in synchronously growing cultures, includes a sequential series of morphological changes that occur at specific times in the cycle and at specific locations in the cell. The Shapiro Lab is packing up shop to move to California! We take advantage of the best feature of both model and non-model organisms, including laboratory mice, wild stickleback fish, and pluripotent stem cells from humans and non-human primates. She was a psychologist, did some work at in Materials Science & Engineering, Stanford . View details for DOI 10.1073/pnas.1433105100. Regulated timing of these cellular modules stems from global genetic circuits that allow precise temporal activation with respect to cell cycle progression and cell differentiation. While super-resolution imaging has greatly benefited from highly photostable fluorophores, a shortage of photostable fluorescent labels for bacteria has limited its use in these small but relevant organisms. The position of genetic loci on the chromosome is thereby linearly correlated with their position in the cell. 2017 Indian Institute of Technology, University of Wisconsin-Madison (1-3) In the alpha-proteobacterium, Caulobacter crescentus, the CtrA global transcriptional regulator exhibits a spatially and temporally dynamic expression pattern across the cell cycle. In this perspective, we highlight recent discoveries in Caulobacter crescentus asymmetric cell division to illuminate diverse mechanisms by which a cellular compass, composed of scaffolding and signaling proteins, directs cell cycle modules to their exact cellular addresses. 1) Cell populations can be synchronized, and homogeneous populations at each stage in the differentiation cycle can thus be obtained. The flagellum is composed of a transmembrane basal body, a hook and a filament. We have succeeded in isolating synchronized populations of Agrobacterium cells and analyzing their progression through the cell cycle. In this report we identify a cluster of genes encoding basal body components and describe their transcriptional regulation. Gober, J. W., CHAMPER, R., Reuter, S., Shapiro, L. IDENTIFICATION OF CIS AND TRANS-ELEMENTS INVOLVED IN THE TIMED CONTROL OF A CAULOBACTER FLAGELLAR GENE. On the other hand, several differences were found between the C. crescentus and E. coli RNA polymerases with respect to their interaction with Caulobacter phage phiCdl DNA. B.S. Stanford Center for Societal Networks. B.S. Ben Shapiro will speak at a free event on campus. The flaD gene was cloned and characterized by nucleotide sequencing and S1 nuclease protection assays. A deletion of the ssrA gene, or of the gene encoding SmpB, a protein required for SsrA activity, results in a specific delay in the cell cycle during the G(1)-to-S transition. Included are those involved in chemotaxis, outer membrane channel function, degradation of aromatic ring compounds, and the breakdown of plant-derived carbon sources, in addition to many extracytoplasmic function sigma factors, providing the organism with the ability to respond to a wide range of environmental fluctuations. A fatty acid auxotroph of Caulobacter crescentus, AE6001, which displays a strict requirement for unsaturated fatty acids to grow on glucose as the carbon source has been isolated. A nitrogen regulatory circuit can be regulated by the intracellular level of tryptophan, which mimics the allosteric role of glutamine in this feedback loop. Cell division yields dissimilar daughter cells: a stalked cell and a swarmer cell that assembles several pili at the flagellated cell pole. A newly discovered NAP in Caulobacter crescentus, GapR, is thought to facilitate the movement of the replication and transcription machines along the chromosome by stimulating type II topoisomerases to remove positive supercoiling. These ternary complexes aggregate predominantly at the cell poles. The Department is a dynamic, interactive research community situated in one of the world's best environments for biomedical research. To explore the global extent of this regulatory mechanism, we determined the methylation state of the entire chromosome at every base pair at five time points in the cell cycle using single-molecule, real-time sequencing. The significance of this study is the identification of structural elements involved in the oligomerization and DNA binding of a newly discovered NAP in C. crescentus and the demonstration that structural elements are conserved in evolutionarily distant and functionally distinct NAPs. RNA polymerase-binding studies with restriction fragments of the rRNA gene cluster revealed three regions which bound enzyme, and these regions were shown to contain transcription initiation sites. Run two-sample ttests, paired ttests, and one-sample ttests in SAS and SAS EG using PROC TTEST. For DNA segments greater than about 300 kb, the mean interloci distances scale as n, in agreement with previous observations. 2020: 1558944720928489, Hand (New York, N.Y.) -Alokozai, A., Lindsay, S. E., Eppler, S. L., Fox, P. M., Ladd, A. L., Kamal, R. N.2019: 1558944719890039, Computer methods in biomechanics and biomedical engineering. The analysis of small predivisional vesicles showed that the MCP content is higher in the flagellated vesicles, and analysis of large flagellated vesicles showed that the MCPs are positioned preferentially in the swarmer cell portion of the predivisional cell. Electron micrographs reveal the phage to be among the largest DNA bacteriophages reported, with head dimensions of 64 by 195 nm and a flexible tail 275 nm in length. Deoxyribonucleic acid-dependent ribonucleic acid (RNA) polymerase (EC 2.7.7.6) was purified from the dimorphic bacterium Caulobacter crescentus at three stages in development. We propose that pole-specific control of PopZ function co-ordinates polar development and cell cycle progression by enabling independent assembly and tethering activities at the two cell poles. This 37,000 Mr heat-shock protein might be related to the E. coli 32,000 Mr heat-shock sigma subunit. Low levels of the L-ring protein were detected exclusively in the cell envelope of cells lacking the P-ring, suggesting that, in the absence of P-ring assembly, L-ring monomers are unable to form multimeric rings and are thus subject to proteolysis in the periplasm. Transcription initiation from this region was also detected in vivo, when the cloned rRNA gene cluster was present on a multi-copy plasmid. CtrA functions as a silencer of the replication origin and GcrA as an activator of components of the replisome and the segregation machinery. Hierarchical formation of higher-order SpmX oligomers nucleates new PopZ microdomain assemblies at the incipient lateral cell poles, driving localized outgrowth. The relative order of the cleavage fragments was determined by specific cleavage of isolated restriction fragments, terminal labeling of both the whole genome and isolated fragments, and hybridization of isolated fragments to restriction fragments generated by other restriction enzymes. After phage infection at least 40 proteins are phosphorylated; these include DNA-binding proteins, a membrane-associated protein, and several ribosomal proteins. Z., Dill, D. L., McAdams, H. H., Shapiro, L. A pseudokinase couples signaling pathways to enable asymmetric cell division in a bacterium. 194:91-103, 1987). The transduction of the chemotaxis signal is initiated by a chemoreceptor-CheW-CheA ternary complex at the inner membrane. The probe correlation analysis approach reported here is of general use for large-scale sRNA identification for any sequenced microbial genome. The site facilitates research and collaboration in academic endeavors. Previous microarray experiments revealed that several Caulobacter genes are significantly upregulated in response to uranium but not in response to other heavy metals. The signal mediators, proteases, response regulators, and kinases, as well as Cori DNA and the replisome, all show distinct patterns of temporal and spatial organization during cell cycle progression.

View details for DOI 10.1371/journal.pgen.1004831, View details for PubMedCentralID PMC4287350. Since SpoT controls (p)ppGpp abundance, we propose that this nucleotide relays carbon starvation signals to the cellular factors responsible for activating DnaA proteolysis, thereby inhibiting the initiation of DNA replication. The transient accumulation of DivL at the new cell pole, but not its kinase activity, is required for the localization and activation of CckA. The distinct control of available CcrM in progeny swarmer and stalked cells serves to protect the hemimethylated state of DNA during chromosome replication, enabling robustness of cell cycle progression. Like some of the proteins in the heat-shock protein families of Drosophila and yeast, the four heat-shock proteins in C. crescentus were found to be regulated developmentally under normal conditions. Using functional genomic analysis, Trisha compared the molecular wounding responses between regenerative and non-regenerative flatworms. Our results broadly demonstrate how signaling factors can leverage information from their subcellular niche to drive spatiotemporal control of cell signaling. Mann, T.

This study reports the identification and functional characterization of a vanillate-regulated promoter (P(van)) which meets all requirements for application as a multi-purpose expression system in Caulobacter, thus complementing the established xylose-inducible system (P(xyl)). Spatial control of intracellular signaling relies on signaling proteins sensing their subcellular environment. Biteen, J. S., Goley, E. D., Shapiro, L., Moerner, W. E. Structure of the pilus assembly protein TadZ from Eubacterium rectale: implications for polar localization. Postdoctoral Scholar Gevaert Lab. Antigen-antibody complex formation occurring within a vector-phage plaque can be used to detect the production of a specific protein from an amplified gene. The dynamic subcellular localization of protein complexes is an integral feature of regulatory processes of bacterial cells. Oleic acid repressed fatty acid biosynthesis and induced fatty acid degradation in the wild-type parent, AE5000 . Bacteria exhibit a high degree of intracellular organization, both in the timing of essential processes and in the placement of the chromosome, the division site, and individual structural and regulatory proteins. These defects include a frequent failure to complete cell division and loss of precise cell-cycle control of initiation of DNA replication. View details for Web of Science ID 000361534800042, View details for PubMedCentralID PMC4541484. The deoxyribonucleic acid of the dimorphic bacterium Caulobacter crescentus contains a component that renatures with rapid, unimolecular kinetics. Big Moerner Lab crew spanning two generations at the GRC on Single Molecule Approaches to Biology, Mt. (2021). Stanford Clinical Pathology offers a wide range of routine & esoteric testing. Phage phiCb5 was studied with respect to the physical and chemical properties of both the phage and its RNA. The cell cycle arrest therefore results from nutritional deprivation and is analogous to the general control system exhibited by yeast (Hartwell, Bacteriol. While recent advances in cryogenic electron microscopy (cryo-EM) allow for the visualization and identification of structures within cells at the nanometer scale, information regarding the cellular environment, such as pH, membrane potential, ionic strength etc. CtrA activity must be removed from cells at the onset of DNA replication, because phosphorylated CtrA binds to and silences the origin of replication. 7/2016. Because of the many parallels in the function of these biochemically based genetic circuits and electrical circuits, a hybrid modeling approach is proposed that integrates conventional biochemical kinetic modeling within the framework of a circuit simulation. The DnaA regulon includes genes encoding several replisome components, the GcrA global cell cycle regulator, the PodJ polar localization protein, the FtsZ cell division protein, and nucleotide biosynthesis enzymes. Regulated proteolysis is essential for cell cycle progression in both prokaryotes and eukaryotes. We have isolated DNA from this region of the chromosome by using a nonmotile mutant with a Tn5 insertion into flaE. The transposons were altered so that upon insertion into the chromosome, transcription fusions are formed in which the promoter regions of fla genes drive the expression of the downstream promoter-less drug resistance genes. In addition, the effects of ionic strength on the time course of polymerization varied both with the sources of bacterial polymerase and bacteriophage DNA. In progeny stalked cells, however, accumulated CcrM that has not been degraded before the immediate initiation of DNA replication is sequestered to the cell pole. To define the mechanisms that mediate this temporal and spatial control, fla genes whose products are not known were accessed by the insertion of transposon-carried drug resistance markers. von Diezmann, A., Lasker, K., Mann, T. H., Ahrens, D. G., Shapiro, L., Moerner, W. E. Probing Asymmetric Behavior of a Cell Cycle Regupatory Protein in Live Caulobacter using Single-Molecule Imaging, A Red Fluorescent Protein for Cryogenic Single-Molecule Superresolution Imaging. Our analysis defines a new class of bacterial origins and suggests a coupling between transcription and replication that is consistent with the phylogenetic relationship of Caulobacter to the ancestral mitochondrion. B.S. DNA replication in the dimorphic bacterium Caulobacter crescentus is tightly linked to its developmental cell cycle. Little is known about the structure and function of most nucleoid-associated proteins (NAPs) in bacteria. Because typical organic fluorophores can emit significantly more photons than average fluorescent proteins, organic fluorophores have a potential advantage in super-resolution imaging schemes, but targeting to specific cellular proteins must be provided. Shapiro, L., Grossman, L. I., Marmur, J., KLEISCHM, A. K. SYMPOSIUM ON REPLICATION OF VIRAL NUCLEIC ACIDS .2. Determination of the DivL crystal structure and biochemical analysis of wild-type and site-specific DivL mutants revealed that the DivL PAS domains regulate binding specificity for DivKP over DivK, which is modulated by an allosteric intramolecular interaction between adjacent domains. The rapid synchronizability and high cell yields of Caulobacter make this organism a powerful model system for studies of the bacterial cell cycle. Because of its critical role, CtrA activity is temporally regulated by multiple mechanisms including phosphorylation and ClpXP-dependent degradation of CtrA.
