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 an appropriate response to DNA damage and contributes to genomic stability. Additionally, RPA2 is involved in other cellular processes, including the maintenance of telomeres and DNA damage checkpoints.
