Gene_symbol  
Summary  The protein encoded by this gene is found in the nucleus and is a cofactor of DNA polymerase delta.The encoded protein acts as a homotrimer and helps increase the processivity of leading strand synthesis during DNA replication.In response to DNA damage,this protein is ubiquitinated and is involved in the RAD6-dependent DNA repair pathway.Two transcript variants encoding the same protein have been found for this gene.Pseudogenes of this gene have been described on chromosome 4 and on the X chromosome.[provided by RefSeq,Jul 2008]
UniPort summary  Function  Auxiliary protein of DNA polymerase delta and is involved in the control of eukaryotic DNA replication by increasing the polymerase´s processibility during elongation of the leading strand.Induces a robust stimulatory effect on the 3´-5´ exonuclease and 3´-phosphodiesterase,but not apurinic-apyrimidinic (AP) endonuclease,APEX2 activities.Has to be loaded onto DNA in order to be able to stimulate APEX2.Plays a key role in DNA damage response (DDR) by being conveniently positioned at the replication fork to coordinate DNA replication with DNA repair and DNA damage tolerance pathways.Acts as a loading platform to recruit DDR proteins that allow completion of DNA replication after DNA damage and promote postreplication repair:Monoubiquitinated PCNA leads to recruitment of translesion (TLS) polymerases,while ´Lys-63´-linked polyubiquitination of PCNA is involved in error-free pathway and employs recombination mechanisms to synthesize across the lesion.
