Background Information RPA 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), and plays multiple roles in DNA metabolism. RPA is required for DNA replication initiation, as well as replication elongation. At the onset of DNA replication, RPA is loaded onto chromatin after the binding of Cdc45 to origins. RPA is needed for subsequent loading of DNA polymerase and other replication proteins to initiate DNA replication. After DNA 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 in response to DNA damage by ATM, ATR, and DNA-PK. Alternate names for RPA32 include replication protein A 32 kDa subunit, RP-A, RF-A, replication factor-A protein 2, p32, p34, RPA2, REPA2, and RPA32.

UniProt Number
UniProt Summary FUNCTION: Required for DNA recombination, repair and replication. The activity of RP-A is mediated by single-stranded DNA binding and protein interactions.

SUBUNIT STRUCTURE: Heterotrimer of 70, 32 and 14 kDa chains. The DNA-binding activity may reside exclusively on the 70 kDa subunit. Binds to SERTAD3/RBT1. Interacts with TIPIN.

SUBCELLULAR LOCATION: Nucleus. Note: Also present in PML nuclear bodies. Redistributes to discrete nuclear foci upon DNA damage.

PTM: Phosphorylated in a cell-cycle-dependent manner (from the S phase until mitosis). Phosphorylated by ATR upon DNA damage, which promotes its translocation to nuclear foci. Can be phosphorylated in vitro by PRKDC/DNA-PK in the presence of Ku and DNA, and by CDC2.
