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:
chpBToxin of the ChpB-ChpS toxin-antitoxin system; Toxic component of a type II toxin-antitoxin (TA) system. ChpB is a sequence-specific mRNA and (weak) tmRNA endoribonuclease that inhibits protein synthesis and induces bacterial stasis. Cleavage is independent of the ribosome. Cleavage occurs at ACY sequences where Y is not C. The endoribonuclease activity is not as strong as that of MazF. The endoribonuclease activity (a toxin) is inhibited by its labile cognate antitoxin ChpS. Toxicity results when the levels of ChpS decrease in the cell, leading to mRNA degradation. Both ChpS and ChpB [...] (116 aa)
ssnAPutative chlorohydrolase/aminohydrolase; Protein involved in cell cycle. (442 aa)
yhaVToxin of the SohB(PrlF)-YhaV toxin-antitoxin system; Toxic component of a type II toxin-antitoxin (TA) system. Has RNase activity in vitro. Overexpression leads to growth arrest after 30 minutes; these effects are overcome by concomitant expression of antitoxin SohA (PrlF). Massive overexpression is toxic. Unlike most other characterized TA systems degrades rRNA, and co-folding of the both TA proteins is necessary in vitro for inhibition of the RNase activity. It is not known if it has any sequence-specificity. Acts as a transcription factor. The YhaV/PrlF complex binds the prlF-yhaV o [...] (154 aa)
ybjNNegative regulator of motility; Putative sensory transduction regulator. (158 aa)
ykfIToxin YkfI; Toxic component of a type IV toxin-antitoxin (TA) system. Acts as a toxin inhibitor that blocks cell division and cell elongation via FtsZ and possibly also MreB (although no interaction with MreB has been proven). Overexpression results in inhibition of growth in liquid cultures and a decrease in colony formation. These effects are overcome by concomitant expression of cognate antitoxin YafW, which leads to toxin loss by an unknown mechanism. Overexpression leads to formation of lemon-shaped cells and cell lysis; inactivated by overexpression of cognate antitoxin YafW but [...] (113 aa)
mazFmRNA interferase toxin, antitoxin is MazE; Toxic component of a type II toxin-antitoxin (TA) system. A sequence-specific endoribonuclease it inhibits protein synthesis by cleaving mRNA and inducing bacterial stasis. It is stable, single- strand specific with mRNA cleavage independent of the ribosome, although translation enhances cleavage for some mRNAs. Cleavage occurs at the 5'-end of ACA sequences, yielding a 2',3'-cyclic phosphate and a free 5'-OH, although cleavage can also occur on the 3'-end of the first A. Digests 16S rRNA in vivo 43 nts upstream of the C- terminus; this remove [...] (111 aa)
