Background Information

RPA4, also named as RP-A p30, is a 261 amino acid protein, which belongs to the replication factor A protein 2 family. RPA4 is preferentially expressed in placental and colon mucosa. RPA4 as part of the alternative replication protein A complex, aRPA, binds single-stranded DNA and probably plays a role in DNA repair. This protein, Rpa4, has 47% identity with Rpa2, the 34-kDa subunit of RPA. (PMID: 7760808)
