Summary: Enables double-stranded DNA binding activity; sequence-specific DNA binding activity; and single-stranded DNA binding activity. Involved in DNA metabolic process; establishment of protein localization; and protein ubiquitination. Acts upstream of with a positive effect on positive regulation of DNA helicase activity and positive regulation of endodeoxyribonuclease activity. Located in chromosome, telomeric region; condensed nuclear chromosome; and cytosol. Part of DNA replication factor A complex. Orthologous to human RPA1 (replication protein A1).

Preferred Names: replication factor A subunit protein RFA1

NP_009404.1

Subunit of heterotrimeric Replication Protein A (RPA); RPA is a highly conserved ssDNA binding protein involved in DNA replication, repair, and recombination; RPA protects against inappropriate telomere recombination, and upon telomere uncapping, prevents cell proliferation by a checkpoint-independent pathway; promotes recruitment, helicase and nuclease activities of Dna2p; role in DNA catenation/decatenation pathway of chromosome disentangling; relocalizes to the cytosol in response to hypoxia
