Background of RPA1 antibody

RPA70 (HSSB, REPA1, RF-A, RP-A, p70) is a component of a heterotrimeric complex, composed of 70, 32/30 and 14 kDa subunits, collectively known as RPA. RPA is a single stranded D binding protein, whose D binding activity is believed to reside entirely in the 70 kDa subunit. The complex is required for almost all aspects of cellular D metabolism such as D replication, recombition, cell cycle and D damage checkpoints, and all major types of D repair including nucleotide excision, base excision, mismatch and double-strand break repairs. In response to genotoxic stress in eukaryotic cells, RPA has been shown to associate with the Rad9/Rad1/Hus1 checkpoint complex. RPA is hyperphosphorylated upon D damage or replication stress by checkpoint kises including ataxia telangiectasia mutated (ATM), ATM and Rad3-related (ATR), and D-dependent protein kise (D-PK). Hyperphosphorylation may alter RPA-D and RPA-protein interactions. In addition to the checkpoint partners, RPA interacts with a wide variety of protein partners, including proteins required for normal replication such as RCF, PC and Pol a, and also proteins involved in SV40 replication, such as D polymerase I and SV40 large T antigen .
