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

MTH_550DNA-dependent DNA polymerase family X; Function Code:10.09 - Metabolism of Macromolecules, DNA replication--modification--repair--and recombination; similar to, gp:GI:e255092:g1770035 LN:BSZ75208, p()=9.1E-56, pid=43%. (550 aa)    
Predicted Functional Partners:
lig
DNA ligase; DNA ligase that seals nicks in double-stranded DNA during DNA replication, DNA recombination and DNA repair.

MTH_212
Exodeoxyribonuclease; Involved in DNA uracil repair. Recognizes DNA uracil residues within double-stranded DNA and initiates DNA-U repair by endonucleotic incision on the 5'-side of the 2'-d-uridine residue, irrespective of the nature of the opposing nucleotide. In addition, acts as an apurinic/apyrimidinic (AP) endonuclease hydrolyzing the DNA phosphodiester backbone immediately at the 5'-side of AP sites, and as a 3'-5' exonuclease. Strongly binds to double-stranded DNA.

fen
DNA repair protein Rad2; 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 (BER) pathwa [...]

pcn
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 (By similarity). In conjunction with replication factor C (RFC) stimulates DNA synthesis by PolB, relieving inhibition by replication protein A (RPA). Belongs to the PCNA family.
    
 0.877
mutS2
DNA mismatch recognition protein MutS; Has ATPase and non-specific DNA-binding activities. Belongs to the DNA mismatch repair MutS family. Archaeal Muts2 subfamily.
  
  
 0.713
polB
DNA polymerase delta small subunit; 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 (By similarity); Belongs to the DNA polymerase delta/II small subunit family.

MTH_1384
Replication factor A related protein; Function Code:10.09 - Metabolism of Macromolecules, DNA replication--modification--repair--and recombination; similar to, pir:LN:F64444 AC:F64444, p()=0.0000042, pid=21%.
   
 0.676
rpa
Replication factor A related protein; Inhibits DNA polymerase activity of PolB, which can be overcome by RFC and PNCA. Stimulates 3'-to 5'-exonuclease activity of PolB at 30 degrees Celsius, but has no effect at 50 or 70 degrees Celsius. Bind ssDNA and replication forks; replication forks structures bind both Hel308 and this protein. Has no effect on helicase activity of Hel308; may help target the helicase to DNA substrates that require DNA re-modeling.

polB1
DNA-dependent DNA polymerase family B (PolB1); In addition to polymerase activity, this DNA polymerase exhibits 3'-5' exonuclease activity; Belongs to the DNA polymerase type-B family.
  
 0.645
polB2
DNA-dependent DNA polymerase family B (PolB2); In addition to polymerase activity, this DNA polymerase exhibits 3'-5' exonuclease activity.
