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

mutSMethyl-directed mismatch repair protein; This protein is involved in the repair of mismatches in DNA. It is possible that it carries out the mismatch recognition step. This protein has a weak ATPase activity. (853 aa)    
Predicted Functional Partners:
mutL
Methyl-directed mismatch repair protein; This protein is involved in the repair of mismatches in DNA. It is required for dam-dependent methyl-directed DNA mismatch repair. May act as a 'molecular matchmaker', a protein that promotes the formation of a stable complex between two or more DNA-binding proteins in an ATP-dependent manner without itself being part of the final effector complex. The ATPase activity of MutL is stimulated by DNA.

dnaN
DNA polymerase III, beta subunit; Confers DNA tethering and processivity to DNA polymerases and other proteins. Acts as a clamp, forming a ring around DNA (a reaction catalyzed by the clamp-loading complex) which diffuses in an ATP- independent manner freely and bidirectionally along dsDNA. DNA bound in the ring is bent 22 degrees, in solution primed DNA is bound more tightly than dsDNA, suggesting the clamp binds both ss- and dsDNA. In a complex of DNA with this protein, alpha, epsilon and tau subunits however the DNA is only slightly bent. Coordinates protein traffic at the replicati [...]

polA
5' to 3' DNA polymerase and 3' to 5'/5' to 3' exonuclease; In addition to polymerase activity, this DNA polymerase exhibits 3'-5' and 5'-3' exonuclease activity. It is able to utilize nicked circular duplex DNA as a template and can unwind the parental DNA strand from its template.
  
 0.906
ygdG
Ssb-binding protein, misidentified as ExoIX; Has flap endonuclease activity , but does not seem to have exonuclease activity (and. During DNA replication, flap endonucleases cleave the 5'-overhanging flap structure that is generated by displacement synthesis when DNA polymerase encounters the 5'-end of a downstream Okazaki fragment.
   
 0.850
mfd
Transcription-repair coupling factor; Couples transcription and DNA repair by recognizing RNA polymerase (RNAP) stalled at DNA lesions. Mediates ATP-dependent release of RNAP and its truncated transcript from the DNA, and recruitment of nucleotide excision repair machinery to the damaged site. Can also dissociate RNAP that is blocked by low concentration of nucleoside triphosphates or by physical obstruction, such as bound proteins. In addition, can rescue arrested complexes by promoting forward translocation. Has ATPase activity, which is required for removal of stalled RNAP, but seem [...]

uvrC
Excinuclease UvrABC, endonuclease subunit; The UvrABC repair system catalyzes the recognition and processing of DNA lesions. UvrC both incises the 5' and 3' sides of the lesion. The N-terminal half is responsible for the 3' incision and the C-terminal half is responsible for the 5' incision.
 
  
 0.796
mutH
Methyl-directed mismatch repair protein; Sequence-specific endonuclease that cleaves unmethylated GATC sequences. It is involved in DNA mismatch repair.
    
 0.790
cho
Endonuclease of nucleotide excision repair; Incises the DNA at the 3' side of a lesion during nucleotide excision repair. Incises the DNA farther away from the lesion than UvrC. Not able to incise the 5' site of a lesion. In vitro, the incision activity of Cho is UvrA and UvrB dependent. When a lesion remains because UvrC is not able to induce the 3' incision, Cho incises the DNA. Then UvrC makes the 5' incision. The combined action of Cho and UvrC broadens the substrate range of nucleotide excision repair.
