RPA2 (Replication Protein A2): RPA2 is a subunit of the Replication Protein A (RPA) complex and plays a key role in DNA replication, repair, and recombination. RPA2 helps stabilize and protect single-stranded DNA (ssDNA) during replication, preventing degradation and supporting the recruitment of other DNA repair proteins. Through these actions, it ensures proper DNA damage response and contributes to genomic stability. Additionally, RPA2 is involved in other cellular processes, including telomere maintenance and DNA damage checkpoints.
