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

priSDNA primase, small subunit; 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. [...] (323 aa)    
Predicted Functional Partners:
priL
Unknown; 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.

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.
  
 0.996
polB2
DNA-dependent DNA polymerase family B (PolB2); In addition to polymerase activity, this DNA polymerase exhibits 3'-5' exonuclease activity.
  
 0.996
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.
 
 
 0.989
rnhB
Ribonuclease HII; Endonuclease that specifically degrades the RNA of RNA-DNA hybrids; Belongs to the RNase HII family.
  
  
 0.957
MTH_1770
Function Code:10.09 - Metabolism of Macromolecules, DNA replication--modification--repair--and recombination; similar to, sp:LN:C21H_HUMAN AC:P33991, p()=4.2E-104, pid=38%; Belongs to the MCM family.
  
 0.954
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.
  
 0.943
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 [...]

rfcS
Replication factor C, small subunit; Part of the RFC clamp loader complex which loads the PCNA sliding clamp onto DNA. The complex possesses DNA-dependent ATPase activity which is further stimulated by PCNA. In conjunction with PCNA stimulates DNA synthesis by PolB, relieving inhibition by replication protein A (RPA); Belongs to the activator 1 small subunits family. RfcS subfamily.
  
 0.929
cdc6-2
Cdc6 related protein; Involved in regulation of DNA replication. Dissociates the MCM complex and inhibits the MCM helicase activity, suggesting that it may function as a helicase loader. Binds to both specific and random double-stranded or single-stranded DNA. Belongs to the CDC6/cdc18 family.
