== Function == | |||
[https://www.uniprot.org/uniprot/RFA2_HUMAN RFA2_HUMAN] Required for DNA recombination, repair and replication. The activity of RP-A is mediated by single-stranded DNA binding and protein interactions. Required for the efficient recruitment of the DNA double-strand break repair factor RAD51 to chromatin in response to DNA damage.<ref>PMID:15205463</ref> <ref>PMID:19116208</ref> <ref>PMID:19996105</ref> <ref>PMID:20154705</ref> Functions as component of the alternative replication protein A complex (aRPA). aRPA binds single-stranded DNA and probably plays a role in DNA repair; it does not support chromosomal DNA replication and cell cycle progression through S-phase. In vitro, aRPA cannot promote efficient priming by DNA polymerase alpha but supports DNA polymerase delta synthesis in the presence of PCNA and replication factor C (RFC), the dual incision/excision reaction of nucleotide excision repair and RAD51-dependent strand exchange.<ref>PMID:15205463</ref> <ref>PMID:19116208</ref> <ref>PMID:19996105</ref> <ref>PMID:20154705</ref> | |||
