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

cdc6-1Cell division control 6/orc1 protein homolog (cdc6-1); Involved in regulation of DNA replication. May play essential roles in origin recognition and cell cycle control of replication. Binds to DNA, with a preference for molecules that contain a bubble, a fork, or a tail. Inhibits the binding of the MCM helicase to the origin DNA and strongly inhibits its DNA helicase activity. Also regulates the DNA polymerase and the nuclease activities of PolB1. Stimulates the DNA-binding activity of Cdc6-3. Belongs to the CDC6/cdc18 family. (397 aa)    
Predicted Functional Partners:
MCM
Minichromosome maintenance protein MCM; Presumptive replicative helicase. Has ATPase and DNA helicase activities. The latter preferentially melts 5'-tailed oligonucleotides and is stimulated by the SSB protein (single-stranded DNA binding protein). The active ATPase sites in the MCM ring are formed through the interaction surfaces of two neighboring subunits such that a critical structure of a conserved arginine finger motif is provided in trans relative to the ATP-binding site of the Walker A box of the adjacent subunit. The helicase function is proposed to use a partially sequential [...]

priL
Conserved 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. Possesses a template- independent 3'-terminal nucleotidyl transferase activity.

cdc6-3
Cell division control 6/orc1 protein homolog (cdc6-3); Involved in regulation of DNA replication. May play essential roles in origin recognition and cell cycle control of replication. Binds to DNA, with a preference for molecules that contain a bubble, a fork, or a tail. Inhibits the binding of the MCM helicase to the origin DNA and inhibits its DNA helicase activity. Also regulates the DNA polymerase and the nuclease activities of PolB1. Inhibits the DNA- binding activity of Cdc6-1 and Cdc6-2.

priS
DNA 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 [...]

dpo1
DNA polymerase I (DNA polymerase B1) (dpo1); This polymerase possesses two enzymatic activities: DNA synthesis (polymerase) and an exonucleolytic activity that degrades single-stranded DNA in the 3'- to 5'-direction. DNA polymerase I, DNA ligase and the flap endonuclease may be constitutively associated with the PCNA heterotrimer forming a scanning complex able to couple DNA synthesis and Okazaki fragment maturation.

SSO0256
Conserved hypothetical protein; Belongs to the UPF0215 family.
       0.852
SSB
Single-stranded DNA binding protein (SSB); Binds to ssDNA, binding approximately 5 nucleotides per monomer. Binding my be slightly cooperative. Inhibits the endonuclease activity of XPF.
  
 
 0.788
rad2
DNA repair endo/exonuclease FEN-1 (RAD2) (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 exci [...]
 
  
 0.755
dnaG
Bacterial-like DNA primase (dnaG); RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication. Can use NTPs but not dNTPs. Binds DNA. 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. Belongs to the archaeal DnaG primase family.
