STRINGSTRING
STRING protein interaction network
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

Rv1954cHypothetical protein; Rv1954c, (MTCY09F9.10), len: 173 aa. Hypothetical unknown protein, end overlaps next ORF upstream, Rv1955 (MTCY09F9.09c). (173 aa)    
Predicted Functional Partners:
Rv0061c
Hypothetical protein; Rv0061c, len: 112 aa. Conserved hypothetical protein supported by RNA-seq data. Similar to MMAR_3839, 76% identity in 112 aa overlap. Replaces questionable ORF Rv0061 (MTV030.04).

usfY
Putative protein UsfY; Rv3288c, (MTCY71.28c), len: 137 aa. UsfY, putative protein (see citation below). Has no significant homologues. May not be contranscribed with the usfX and sigF proteins.

higB
Possible 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 [...]

secBL
Hypothetical 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 [...]
