Component of the replication protein A complex (RPA) required for DNA recombination, repair and replication. The activity of RPA is mediated by single-stranded DNA binding and protein interactions. Required fo cell division in meristems. Involved in the maintenance of transcriptional epigenetic gene silencing (TGS) at specific loci (including some transposons) by regulating histone H3 acetylation, 'Lys-4' and 'Lys-9' methylation (By similarity). Heterotrimer of RPA1, RPA2 and RPA3 (canonical replication protein A complex). Redistributes to discrete nuclear foci upon DNA damage. Additional isoforms seem to exist. 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 a hypophosphorylated form (By similarity). Belongs to the replication factor A protein 2 family.
