Rpa2 Gene Summary [Rat]
Enables single-stranded DNA binding activity. Predicted to be involved in several processes, including DNA metabolic process; regulation of cell cycle phase transition; and regulation of double-strand break repair via homologous recombination. Part of DNA replication factor A complex. Orthologous to human RPA2 (replication protein A2). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Rpa2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
