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.

pcn2Proliferating-cell nuclear antigen homolog (PCNA); Sliding clamp subunit that acts as a moving platform for DNA processing. Responsible for tethering the catalytic subunit of DNA polymerase and other proteins to DNA during high-speed replication. Belongs to the PCNA family. (256 aa)    
Predicted Functional Partners:
fen
DNA endonuclease rad2 homolog; 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) [...]
 
 0.971
lig
DNA ligase; DNA ligase that seals nicks in double-stranded DNA during DNA replication, DNA recombination and DNA repair.
   
 0.966
PAE2109
DNA-directed DNA polymerase (B3); DNA metabolism; DNA replication, recombination, and repair.
  
 0.954
rfcL
Replication factor C large subunit; Part of the RFC clamp loader complex which loads the PCNA sliding clamp onto DNA; Belongs to the activator 1 small subunits family. RfcL subfamily.
 
 0.951
priS
DNA primase related protein; Catalytic subunit of DNA primase, an RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication. The small subunit contains the primase catalytic core and has DNA synthesis activity on its own. Binding to the large subunit stabilizes and modulates the activity, increasing the rate of DNA synthesis while decreasing the length of the DNA fragments, and conferring RNA synthesis capability. The DNA polymerase activity may enable DNA primase to also catalyze primer extension after primer synthesis [...]
 
 0.947
PAE2180
DNA-directed DNA polymerase (B1); DNA metabolism; DNA replication, recombination, and repair.
  
 0.944
priL
Conserved protein (possible primase); Regulatory subunit of DNA primase, an RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication. Stabilizes and modulates the activity of the small subunit, increasing the rate of DNA synthesis, and conferring RNA synthesis capability. The DNA polymerase activity may enable DNA primase to also catalyze primer extension after primer synthesis. May also play a role in DNA repair.
 
 0.934
rnhB
Ribonuclease HII (rnhB); Endonuclease that specifically degrades the RNA of RNA-DNA hybrids; Belongs to the RNase HII family.
 
 
 0.931
PAE1113
Possible DNA-directed DNA polymerase (B2); DNA metabolism; DNA replication, recombination, and repair.
 
 0.922
pcn1
Proliferating-cell nuclear antigen homolog (PCNA); Sliding clamp subunit that acts as a moving platform for DNA processing. Responsible for tethering the catalytic subunit of DNA polymerase and other proteins to DNA during high-speed replication. Belongs to the PCNA family.
