rpoE Antibody

1. Mapping of 5' ends of rpoE mRNA identified five new transcriptional initiation sites (P1 to P5) located distal to Esigma(E)-regulated promoter. PMID: 27629414
2. These results demonstrate that appropriate regulation of sigma(E) activity, ensuring that it is neither too high nor too low, is critical for envelope integrity and cell viability. PMID: 28373273
3. This paper describes a unique mutation that enhances kinetics of the rpoE envelope stress response pathway rather than preinducing the response. PMID: 27325680
4. In particular, Esigma(S) appears to contribute significantly to transcription of genes encoding proteins involved in LPS biosynthesis and in cell surface composition. Finally, our results highlight a direct role of Esigma(S) in the regulation of non coding RNAs PMID: 26020590
5. RpoE regulates transcription of the defective prophage DLP12 lysis genes through interaction with QDLP12. PMID: 25998262
6. However, membrane protein damage induced by gentamicin can be eliminated or repaired by RpoE- and Cpx-dependent mechanisms pre-emptively induced in P-starved cells. PMID: 25039943
7. TraR increases the concentrations of periplasmic chaperones and proteases by directly activating the transcription of sigma(E)-dependent promoters. PMID: 25535270
8. The sigma(E) response was activated in Deltahfq mutants of all strains tested, resulting from the misregulation ofouter membrane proteins, whereas the Cpx response was activated by loss of hfq in enteropathogenic strains, but not in E. coli K-12. PMID: 24628810
9. Through employing a labile mutant periplasmic protein, AcrA(L222Q), it was determined that the rpoE3 mutation overcomes the DeltadegP phenotypes, in part, by activating a sigma(E)-dependent proteolytic pathway. PMID: 22439016
10. Taken together, the results suggest that the cell lysis proceeds in the cascade of sigma(E) --> expression of micA and rybB --> reduction in Omp proteins --> disintegration of the outer membrane. PMID: 22251246
11. Recognition of beta-strand motifs of sigma(E) by RseB is required for sigma(E) activity. PMID: 21908666
12. RpoE is required for stress-induced lac amplification. The role of the sigma(E) stress response in mutagenesis is independent of SOS and DinB upregulation, cytoplasmic heat-shock- and RpoS-stress responses. PMID: 20497332
13. Role in resistance to zinc, cadmium, and copper toxicity. PMID: 15774872
14. hypotheses:(1)negatively charged N-terminal domain of sigma(70) is bound in polymerase;(2)rate-determining isomerization involves ejecting this domain, unmasking active site; (3)conversion to RP(o) involves coupled folding of downstream clamp of pol. PMID: 16475805
15. Hfq modulates the sigmaE-mediated envelope stress response and the sigma32-mediated cytoplasmic stress response in Escherichia coli. PMID: 17158661
16. the PDZ domain and loop L3 of DegS define a novel molecular switch allowing strict regulation of the sigmaE stress response system PMID: 17938245
17. when sigma(E) is inhibited, cell envelope stress increases and envelope integrity is lost PMID: 18253509
