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, putative; 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. May [...] (347 aa)    
Predicted Functional Partners:
priL
Hypothetical protein; 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.
  
 0.999
pol
DNA-directed DNA polymerase; In addition to polymerase activity, this DNA polymerase exhibits 3' to 5' exonuclease activity.
  
 0.996
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.
 
 
 0.995
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.
  
 0.984
PF0482
Function Code: 4.2 Cellular Processes: Cell division; (cdc21); Belongs to the MCM family.
  
 0.956
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. Belongs to the activator 1 small subunits family. RfcS subfamily.
   
 0.941
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.
  
 
 0.938
dnaG
Hypothetical protein; RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication. Also part of the exosome, which is a complex involved in RNA degradation. Acts as a poly(A)-binding protein that enhances the interaction between heteropolymeric, adenine-rich transcripts and the exosome.
  
  
 0.934
rfcL
Replication factor C, large 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.
  
 0.900
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 [...]
