Single-stranded DNA-binding protein

UniProtKB accession:  P03696

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Single-stranded DNA-binding protein that participates in viral DNA replication, formation of concatemers, recombination and repair of double-stranded breaks (PubMed:16807232, PubMed:8617248, PubMed:9079662, PubMed:11222583). Coats the lagging-strand ssDNA as the replication fork advances and stimulates the activities of viral DNA polymerase and primase/helicase (PubMed:8617248). Coordinates simultaneous synthesis of leading- and lagging-strands (PubMed:9651583). Together with DNA primase/helicase, promotes pairing of two homologous DNA molecules containing complementary single-stranded regions and mediates homologous DNA strand exchange (PubMed:8617248). Promotes also the formation of joint molecules (PubMed:8617248, PubMed:9079662). Disrupts loops, hairpins and other secondary structures present on ssDNA to reduce and eliminate pausing of viral DNA polymerase at specific sites during elongation (PubMed:1634538).
