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

Rv1049Rv1049, (MTV017.02), len: 148 aa. Probable transcriptional repressor protein, similar to many e.g. P74870 negative regulator of EMR locus EMR from Salmonella typhimurium (149 aa), FASTA scores: opt: 146, E(): 0.0011,(31.6% identity in 95 aa overlap). Contains probable helix-turn-helix motif at aa 58-79 (Score 1495, +4.28 SD). This region is a possible MT-complex-specific genomic island (See Becq et al., 2007). (148 aa)

higBPossible toxin HigB; Toxic component of an atypical, type II toxin-antitoxin chaperone (TAC) system. Upon expression in M.smegmatis inhibits colony formation and cell growth. Ectopic expression in wild-type M.tuberculosis has no effect on cell growth; ectopic expression in a triple higB1-higA1-Rv1957 (delta TAC) disruption mutant causes growth arrest, killing a considerable proportion of the cells. Increased ectopic expression leads to decreased levels of IdeR- and Zur-regulated genes as well as cleavage within the mRNA region of tmRNA (transfer-mRNA), strongly suggesting it is an endo [...] (125 aa)
higAPossible antitoxin HigA; Antitoxin component of an atypical, type II toxin-antitoxin chaperone (TAC) system. Upon expression in M.smegmatis neutralizes the effect of cognate toxin HigB1. Neutralization of HigB1 toxin in E.coli or M.marinum also requires SecB-like chaperone Rv1957, making this the first toxin-antitoxin chaperone (TAC) system. Antitoxin aggregation and degradation are prevented by the chaperone. (149 aa)
secBLHypothetical protein; Chaperone component of an atypical, type II toxin-antitoxin chaperone (TAC) system. Prevents antitoxin HigA1 aggregation in vitro at a 1:3 chaperone:antitoxin ratio, probably also protects antitoxin HigA1 from protease. Required for neutralization of toxin HigB1 upon ectopic expression in Mycobacterium marinum or E.coli. When expressed in E.coli complements a secB deletion, restores export of OmpA and MBP and inhibits aggregation of proOmpC although it is less efficient than endogenous SecB. Complements the general chaperone function of E.coli SecB less well; Belo [...] (181 aa)
