Nuclear PCNA is a marker for cells in early G1 phase and S phase of the cell cycle. It is found in the nucleus and is a cofactor of DNA polymerase delta. It acts as a homotrimer and helps increase the processivity of leading strand synthesis during DNA replication. In response to DNA damage PCNA is ubiquitinated and is involved in the RAD6-dependent DNA repair pathway. Two transcript variants encoding the same protein have been found for PCNA. Pseudogenes of this gene have been described on chromosome 4 and on the X chromosome.

Homotrimer. Interacts with KCTD10. Interacts with PPP1R15A (By similarity). Forms a complex with activator 1 heteropentamer in the presence of ATP. Interacts with POLH POLK DNMT1 ERCC5/XPG FEN1 CDC6 APEX2 and POLDIP2. Interacts with EXO1 and SHPRH. Forms a ternary complex with DNTTIP2 and core histone. Interacts with POLD1 POLD3 and POLD4.

Upon methyl methanesulfonate-induced DNA damage mono-ubiquitinated by the UBE2B-RAD18 complex on Lys-164. This induces non-canonical poly-ubiquitination on Lys-164 through \' Lys-63\' linkage of ubiquitin moieties by the E2 complex UBE2N-UBE2V2 and the E3 ligase SHPRH whih is required for DNA repair.

Belongs to the PCNA family.
