Enables DNA binding activity. Predicted to be involved in several processes, including DNA metabolic process; mitotic G1 DNA damage checkpoint signaling; and regulation of response to DNA damage stimulus. Predicted to act upstream of or within cellular response to DNA damage stimulus. Predicted to be located in PML body and chromatin. Predicted to be part of DNA replication factor A complex. Predicted to be active in chromosome, telomeric region; nucleus; and site of double-strand break. Is expressed in blastocyst; brain; compacted morula; and spermatocyte. Orthologous to human RPA2 (replication protein A2). [provided by Alliance of Genome Resources, Apr 2022]
