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

SSBSingle-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. (148 aa)    
Predicted Functional Partners:
radA
DNA repair protein radA (radA); Involved in DNA repair and in homologous recombination. Binds and assemble on single-stranded DNA to form a nucleoprotein filament. Hydrolyzes ATP in a ssDNA-dependent manner and promotes DNA strand exchange between homologous DNA molecules.

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 [...]

pcnA-1
Proliferating cell nuclear antigen homolog (PCNA) (pcnA-1); One of the sliding clamp subunits that acts as a moving platform for DNA processing. Responsible for tethering the catalytic subunit of DNA polymerase to DNA during high-speed replication. 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. Heterotrimer stimulates the Holliday junction resolvase Hjc.

topA
DNA topoisomerase I family A (topA); Replication and Repair.
 
 0.940
eiF4A
RNA helicase (ATP dependent)/eIF4A (eiF4A); A structure-specific endonuclease, cleaves 5' of ds/ssDNA interfaces in 3' flap structures, although it also cuts bubble, Y-DNA structures and mobile and immobile Holliday junctions. Cuts preferentially after pyrimidines, may continue to progressively cleave substrate upstream of the initial cleavage, at least in vitro. May be involved in nucleotide excision repair.

pcnA-2
Proliferating cell nuclear antigen homolog (PCNA) (pcnA-2); One of the sliding clamp subunits that acts as a moving platform for DNA processing. Responsible for tethering the catalytic subunit of DNA polymerase to DNA during high-speed replication. Heterotrimer stimulates the Holliday junction resolvase Hjc. 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.

rad32/mre11
DNA repair protein (rad32/mre11); Part of the Rad50/Mre11 complex, which is involved in the early steps of DNA double-strand break (DSB) repair. The complex may facilitate opening of the processed DNA ends to aid in the recruitment of HerA and NurA. Mre11 binds to DSB ends and has both double-stranded 3'-5' exonuclease activity and single-stranded endonuclease activity. Belongs to the MRE11/RAD32 family.
   
 0.925
pcnA-like
Proliferating cell nuclear antigen putative homolog (PCNA-like) (pcnA-like); One of the sliding clamp subunits that acts as a moving platform for DNA processing. Responsible for tethering the catalytic subunit of DNA polymerase to DNA during high-speed replication. Heterotrimer stimulates the Holliday junction resolvase Hjc. 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.

radA-like
DNA repair protein radA homolog (radA-like); Bacterial RadA-like (related to bacterial sequences); Replication and Repair.
  
 0.911
rfc
Activator 1, replication factor C, small subunit (rfc); Part of the RFC clamp loader complex which loads the PCNA sliding clamp onto DNA. The complex possesses DNA-dependent ATPase activity; Belongs to the activator 1 small subunits family. RfcS subfamily.
