STRING protein interaction network
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:
some 3D structure is known or predicted
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
protein homology

Gene Fusion
dinIInvolved in SOS regulation. Inhibits RecA by preventing RecA to bind ssDNA. Can displace ssDNA from RecA (81 aa)    
Predicted Functional Partners:
Required for homologous recombination and the bypass of mutagenic DNA lesions by the SOS response. Catalyzes ATP-driven homologous pairing and strand exchange of DNA molecules necessary for DNA recombinational repair. Catalyzes the hydrolysis of ATP in the presence of single-stranded DNA, the ATP-dependent uptake of single- stranded DNA by duplex DNA, and the ATP-dependent hybridization of homologous single-stranded DNAs. The SOS response controls an apoptotic-like death (ALD) induced (in the absence of the mazE-mazF toxin-antitoxin module) in response to DNA damaging agents that is me [...]
Uncharacterized protein YebG; Protein involved in DNA repair and SOS response
Modulates RecA activity through direct physical interaction. Can inhibit both RecA recombinase and coprotease activities. May have a regulatory role during the SOS response. Inhibits DNA strand exchange in vitro
Represses a number of genes involved in the response to DNA damage (SOS response), including recA and lexA. Binds to the 16 bp palindromic sequence 5'-CTGTATATATATACAG-3'. In the presence of single- stranded DNA, RecA interacts with LexA causing an autocatalytic cleavage which disrupts the DNA-binding part of LexA, leading to derepression of the SOS regulon and eventually DNA repair. Implicated in hydroxy radical-mediated cell death induced by hydroxyurea treatment .The SOS response controls an apoptotic-like death (ALD) induced (in the absence of the mazE-mazF toxin-antitoxin module) [...]
Involved in UV protection and mutation. Poorly processive, error-prone DNA polymerase involved in translesion repair . Essential for induced (or SOS) mutagenesis. Able to replicate DNA across DNA lesions (thymine photodimers and abasic sites, called translesion synthesis) in the presence of activated RecA; efficiency is maximal in the presence of the beta sliding-clamp and clamp-loading complex of DNA polymerase III plus single-stranded binding protein (SSB) . RecA and to a lesser extent the beta clamp-complex may target Pol V to replication complexes stalled at DNA template lesions .
May be involved in recombination
Catalyzes the reversible cyclization of carbamoyl aspartate to dihydroorotate
May be involved in recombinational repair of damaged DNA
Protein involved in DNA repair
The RecF protein is involved in DNA metabolism; it is required for DNA replication and normal SOS inducibility. RecF binds preferentially to single-stranded, linear DNA. It also seems to bind ATP
