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

vapB34Possible antitoxin VapB34; Antitoxin component of a possible type II toxin-antitoxin (TA) system. The cognate toxin is VapC34. (70 aa)    
Predicted Functional Partners:
vapC34
Possible toxin VapC34. Contains PIN domain; Toxic component of a possible type II toxin-antitoxin (TA) system. A putative RNase. Its cognate antitoxin is VapB34 (By similarity).; Belongs to the PINc/VapC protein family.
  
 
 0.972
vapC30
Possible toxin VapC30. Contains PIN domain; Toxic component of a type II toxin-antitoxin (TA) system. An RNase (By similarity). Upon expression in M.smegmatis inhibits colony formation. Its toxic effect is neutralized by coexpression with cognate antitoxin VapB30.; Belongs to the PINc/VapC protein family.
  
 
 0.943
vapC4
Possible toxin VapC4; Toxic component of a type II toxin-antitoxin (TA) system. Probably exerts its toxic effect by binding to mRNA, inhibiting translation. Binds to, recognizes and cleaves ssRNA at ACGC and AC(A/U)GC sequences, usually between the G and C; cleavage is not very efficient, nor is cleavage required to inhibit protein synthesis. Upon expression in situ, in M.smegmatis or E.coli inhibits cell growth and colony formation; in at least E.coli also causes increased levels of cellular RNA. Its toxic effect is neutralized by coexpression with cognate antitoxin VapB4.

Rv0273c
Rv0273c, (MTV035.01c), len: 206 aa (start uncertain). Possible transcriptional regulator, showing some similarity to hypothetical regulators from Mycobacterium tuberculosis e.g. P96222|Rv3855|MTCY01A6.13c (216 aa); O08377|Rv1534|MTCY07A7A.03 (225 aa), FASTA scores: opt: 123, E(): 3.2e-06, (28.5% identity in 172 aa overlap).

Rv3488
Conserved hypothetical protein; May have transcription regulation and metal-detoxifying functions through which it may enhance intracellular survival of mycobacteria. Binds to its own promoter region and to the Rv1999c promoter region. It displays strong affinity for cadmium ions, but can also bind zinc, manganese and nickel. Expression increases the intracellular survival of recombinant M. smegmatis in murine macrophage cell line and increases its tolerance to cadmium ions.
