Required for DNA recombination, repair and replication. The activity of RP-A is mediated by single-stranded DNA binding and protein interactions. Required for the efficient recruitment of the DNA double-strand break repair factor RAD51 to chromatin in response to DNA damage. Ref.9 Ref.13 Ref.14 Ref.15

Function: Required for DNA recombination, repair and replication. The activity of RP-A is mediated by single-stranded DNA binding and protein interactions. Required for the efficient recruitment of the DNA double-strand break repair factor RAD51 to chromatin in response to DNA damage. Ref.9 Ref.13 Ref.14 Ref.15Functions as component of the alternative replication protein A complex (aRPA). aRPA binds single-stranded DNA and probably plays a role in DNA repair; it does not support chromosomal DNA replication and cell cycle progression through S-phase. In vitro, aRPA cannot promote efficient priming by DNA polymerase alpha but supports DNA polymerase delta synthesis in the presence of PCNA and replication factor C (RFC), the dual incision/excision reaction of nucleotide excision repair and RAD51-dependent strand exchange. Ref.9 Ref.13 Ref.14 Ref.15. Subunit structure: Heterotrimer of 70, 32 and 14 kDa chains (canonical replication protein A complex). Component of the alternative replication protein A complex (aRPA) composed of RPA1, RPA3 and RPA4. The DNA-binding activity may reside exclusively on the 70 kDa subunit. Binds to SERTAD3/RBT1. Interacts with TIPIN. Directly interacts with PPP4R2, but not with SMEK2; this interaction is DNA damage-dependent and leads RPA2 dephosphorylation by PPP4C recruitment. Interacts with RAD51, preferentially when hyperphosphorylated. Directly interacts with RFWD3. Ref.7 Ref.10 Ref.11 Ref.15 Ref.17 Ref.18. Subcellular location: Nucleus. Nucleus PML body. Note: Also present in PML nuclear bodies. Redistributes to discrete nuclear foci upon DNA damage. Ref.8 Ref.15 Ref.17 Ref.18. Post-translational modification: Phosphorylated in a cell-cycle-dependent manner (from the S phase until mitosis). In response to DNA damage, recruited to DNA-repair nuclear foci, as an hypophosphorylated form. The necessary dephosphorylation step is catalyzed by PP4. Subsequent hyperphosphorylation, catalyzed by ATR, is required for RAD51 recruitment to chromatin and efficient DNA repair. Can be phosphorylated in vitro by PRKDC/DNA-PK in the presence of Ku and DNA, and by CDK1. Phosphorylation at Thr-21 depends upon RFWD3 presence. Ref.6 Ref.8 Ref.18
