Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology
Your Input:
fliWAssembly factor of the flagellum; Acts as an anti-CsrA protein, binds CsrA and prevents it from repressing translation of its target genes, one of which is flagellin. Binds to flagellin (hag), which is implicated in polymerization, and participates in the assembly of the flagellum. An antagonist to translational regulator CsrA, it binds CsrA at an allosteric site and non-competitively inhibits CsrA binding to hag RNA. Partner switching by flagellin between FliW and CsrA provides a flagellar assembly checkpoint to tightly control the timing of flagellin synthesis. Flagellin binds to ass [...] (143 aa)
spo0AResponse regulator; May play the central regulatory role in sporulation. It may be an element of the effector pathway responsible for the activation of sporulation genes in response to nutritional stress. Spo0A may act in concert with Spo0H (a sigma factor) to control the expression of some genes that are critical to the sporulation process. Repressor of abrB, activator of the spoIIa operon. Binds the DNA sequence 5'-TGNCGAA-3' (0A box). (267 aa)
lrgAAntiholin factor; Inhibits the expression or activity of extracellular murein hydrolases by interacting, possibly with LrgB, with the holin-like protein CidA. The LrgAB and CidA proteins may affect the proton motive force of the membrane. May be involved in programmed cell death (PCD), possibly triggering PCD in response to antibiotics and environmental stresses; Belongs to the CidA/LrgA family. LrgA subfamily. (146 aa)
hagFlagellin protein; Flagellin is the subunit which polymerizes to form the filaments of bacterial flagella. Assembly into flagella requires FliW. Acts as a homeostatic autoinhibitory regulator to control its own cytoplasmic levels. Partner switching by flagellin between FliW and CsrA provides a flagellar assembly checkpoint to tightly control the timing of flagellin synthesis. Flagellin binds to assembly factor FliW, freeing translation regulator CsrA to repress translation of the flagellin mRNA. When the flagellar hook is assembled flagellin is secreted, depleting intracellular flagell [...] (304 aa)
csrACarbon storage regulator; A translational regulator that binds mRNA to regulate translation initiation and/or mRNA stability. Usually binds in the 5'- UTR at or near the Shine-Dalgarno sequence preventing ribosome-binding, thus repressing translation. Represses expression of flagellin (hag) in a post-transcriptional fashion. Specifically binds to 2 sites in the 5'-UTR of hag mRNA in a cooperative fashion; the second site overlaps the Shine-Dalgarno sequence and prevents 30S ribosomal subunit binding. Mutation of either binding site abolishes CsrA regulation of hag expression. Repressio [...] (74 aa)
cidAHolin regulator of murein hydrolases; Increases the activity of extracellular murein hydrolases possibly by mediating their export via hole formation. Inhibited by the antiholin-like proteins LrgAB. In an unstressed cell, the LrgAB products probably inhibit the function of the CidA protein. When a cell is stressed by the addition of antibiotics or by other factors in the environment, CidA possibly oligomerizes within the bacterial cell membrane, creating lesions that disrupt the proton motive force, which in turn results in loss of cell viability. These lesions are also hypothesized to [...] (128 aa)
yxzKPutative integral inner membrane protein involved in export murein hydrolases; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pt: putative transporter. (134 aa)
