Replication factor C subunit 5 is a protein that in humans is encoded by the RFC5 gene.^[1][2]

Function

The elongation of primed DNA templates by DNA polymerase delta and DNA polymerase epsilon requires the accessory proteins proliferating cell nuclear antigen (PCNA) and replication factor C (RFC). RFC, also named activator 1, is a protein complex consisting of five distinct subunits of 140, 40, 38, 37, and 36 kD. This gene encodes the 36 kD subunit. This subunit can interact with the C-terminal region of PCNA. It forms a core complex with the 38 and 40 kDa subunits. The core complex possesses DNA-dependent ATPase activity, which was found to be stimulated by PCNA in an in vitro system. Alternatively spliced transcript variants encoding distinct isoforms have been reported.^[2]

Interactions

RFC5 has been shown to interact with:

• BRD4,^[3]
• CHTF18,^[4]
• PCNA,^[5][6][7]
• RFC2,^[5][8] and
• RFC4.^{[5][8][9][10]}
