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

vapB4Possible antitoxin VapB4; Antitoxin component of a type II toxin-antitoxin (TA) system. Antitoxin that counteracts the effect of its cognate VapC4 toxin. Upon expression in situ, in M.smegmatis or E.coli neutralizes the effect of cognate toxin VapC4. (85 aa)    
Predicted Functional Partners:
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.
  
 
 0.985
vapC5
Possible toxin VapC5; Probable toxic component of a type II toxin-antitoxin (TA) system. The cognate antitoxin is VapB5. Has limited RNase activity on substrates; activity is seen with a VapC5-VapB5 complex.
  
 
 0.805
vapC8
Possible toxin VapC8; Toxic component of a type II toxin-antitoxin (TA) system. An RNase. The cognate antitoxin is VapB8 (By similarity); Belongs to the PINc/VapC protein family.
   
 
 0.804
vapC23
Possible toxin VapC23; Toxic component of a type II toxin-antitoxin (TA) system. An RNase. The cognate antitoxin is VapB23 (By similarity). Belongs to the PINc/VapC protein family.
     
 0.631
vapB34
Possible antitoxin VapB34; Antitoxin component of a possible type II toxin-antitoxin (TA) system. The cognate toxin is VapC34.
      
 0.628
vapB29
Possible antitoxin VapB29; Possibly the antitoxic component of a type II toxin-antitoxin (TA) system. Its cognate toxin is VapC29.
      
 0.548
vapC14
Possible toxin VapC14; Toxic component of a type II toxin-antitoxin (TA) system. An RNase. The cognate antitoxin is VapB14 (By similarity); Belongs to the PINc/VapC protein family.
   
   0.529
vapC49
Hypothetical alanine rich protein; Toxic component of a type II toxin-antitoxin (TA) system. An RNase. Its cognate antitoxin is VapB49 (By similarity).
  
  
 0.528
vapC47
Possible toxin VapC47. Contains PIN domain; Toxic component of a type II toxin-antitoxin (TA) system. An RNase (By similarity). Upon expression in M.smegmatis inhibits translation and colony formation. Its toxic effect on colony formation is neutralized by coexpression with cognate antitoxin VapB47; the effect on translation has not been tested but is probably neutralized also.; Belongs to the PINc/VapC protein family.
  
  
 0.522
vapB49
Conserved protein; Possibly the antitoxin component of a type II toxin-antitoxin (TA) system. Its cognate toxin is VapC49 (Potential).
