Anti-Replication Protein A Antibody, clone RPA34-19

RPA (RP-A p32) is a heterotrimeric protein complex that binds specifically to single-stranded DNA (ssDNA). It is composed of three subunits: RPA1 (70 kDa), RPA2 (32 kDa), and RPA3 (14 kDa). RPA plays multiple roles in DNA replication. At the onset of DNA replication, RPA is loaded onto chromatin, and is needed for subsequent loading of DNA polymerase and other replication proteins to initiate DNA replication. After replication begins, RPA moves with replication forks, stabilizing ssDNA and assisting in DNA synthesis. In addition to its replication function, RPA is also known to play essential roles in damage repair and recombination. The 32 kDa subunit is phosphorylated by the cdc2 family of kinases when cells enter S-phase; and by ATM, ATR, and DNA-PK proteins in response to DNA damage.
