General description

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.

DNA double-strand breaks (DSBs) are the most severe type of DNA damage and are primarily repaired by non-homologous end joining (NHEJ) and homologous recombination (HR) in the G1 and S/G2 phase, respectively. Although CtBP-interacting protein (CtIP) is crucial in DNA...

PARP1 is the main sensor of single- and double-strand breaks in DNA and, in building chains of poly(ADP-ribose), promotes the recruitment of many downstream signaling and effector proteins involved in the DNA damage response (DDR). We show a robust physical...

CDC7-DBF4 kinase (DDK) initiates DNA replication in eukaryotes by activating the replicative MCM helicase. DDK has diverse and apparently conflicting roles in the replication checkpoint response in various organisms, but the underlying mechanisms are far from settled. We show that...
