The replication system of a cell contains several essential components among which are replication factor A (RFA, RPA, or HeLa cell SSB), PCNA, and replication factor C (RFC) as well as several other proteins. RPA, a multi-subunit protein containing a 70kDa, 34kDa, and 11kDa protein, may play a critical regulatory role in replication based on its functioning during both the initiation and elongation stages of DNA replication. The protein is highly conserved, having been identified in a range of species from yeast (Saccharomyces cerevisiae) to humans. The primary function of RPA appears to be as an auxiliary protein for both DNA polymerase α and δ. RPA undergoes a cell cycle dependent phosphorylation, which is restricted to the p34 protein. In addition to existing as part of the multi-subunit structure, p34 has also been identified as being present in a free, unphosphorylated form. Recent data shows that RPA is restricted to the nucleus and is overexpressed in transformed cells as well as in several tumor cells.
