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

radBRecombinase; Involved in DNA repair and in homologous recombination. May regulate the cleavage reactions of the branch-structured DNA. Has a very weak ATPase activity that is not stimulated by DNA. Binds DNA but does not promote DNA strands exchange. (235 aa)    
Predicted Functional Partners:
fen
Flap structure-specific endonuclease; Structure-specific nuclease with 5'-flap endonuclease and 5'- 3' exonuclease activities involved in DNA replication and repair. During DNA replication, cleaves the 5'-overhanging flap structure that is generated by displacement synthesis when DNA polymerase encounters the 5'-end of a downstream Okazaki fragment. Binds the unpaired 3'-DNA end and kinks the DNA to facilitate 5' cleavage specificity. Cleaves one nucleotide into the double-stranded DNA from the junction in flap DNA, leaving a nick for ligation. Also involved in the base excision repair [...]

PF0020
Hypothetical protein; Function Code: 16.1 Conserved Hypothetical; Belongs to the UPF0173 family.
       0.849
cdc6
Origin recognition protein subunit 1; Involved in regulation of DNA replication. May play essential roles in origin recognition and cell cycle control of replication. Binds specifically to the oriC region, which alters the topological structure of the DNA and introduces localized melting of the DNA duplex. May recruit the MCM helicase onto the oriC region. Shows weak ATPase activity in the absence of DNA. Belongs to the CDC6/cdc18 family.

pcn
Pcna sliding clamp (proliferating-cell nuclear antigen); Sliding clamp subunit that acts as a moving platform for DNA processing. Responsible for tethering the catalytic subunit of DNA polymerase to DNA during high-speed replication. Unlike its eukaryotic paralog, loads on circular DNA without the replication factor C (RFC) clamp loader, although RFC greatly increases loading efficiency. Stimulates the ATPase activity of replication factor C (RFC) in the presence of ssDNA. Stimulates the helicase activity of Hel308 and may alter its substrate specificity.

polB
DNA polymerase II subunit 1; Possesses two activities: a DNA synthesis (polymerase) and an exonucleolytic activity that degrades single-stranded DNA in the 3' to 5' direction. Has a template-primer preference which is characteristic of a replicative DNA polymerase.
  
 
 0.738
PF2020
Replication factor A related protein; Function Code: 11.1 Replication: DNA replication, restriction, modification, recombination, and repair.
  
 0.704
topA
DNA topoisomerase I; Releases the supercoiling and torsional tension of DNA, which is introduced during the DNA replication and transcription, by transiently cleaving and rejoining one strand of the DNA duplex. Introduces a single-strand break via transesterification at a target site in duplex DNA. The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA- (5'-phosphotyrosyl)-enzyme intermediate and the expulsion of a 3'-OH DNA strand. The free DNA strand then undergoes passage around the unbroken strand, thus removing DNA supe [...]

polC
DNA polymerase II subunit 2; Possesses two activities: a DNA synthesis (polymerase) and an exonucleolytic activity that degrades single-stranded DNA in the 3'- to 5'-direction. Has a template-primer preference which is characteristic of a replicative DNA polymerase.
     
 0.676
pol
DNA-directed DNA polymerase; In addition to polymerase activity, this DNA polymerase exhibits 3' to 5' exonuclease activity.

PF0670
RNase l inhibitor; Function Code: 10 Regulatory Functions: REGULATORY FUNCTIONS.
