Western blot using PCNA polyclonal antibody (Cat # PAB10307) shows detection of PCNA protein in HEK293 (Lane 1) and Jurkat (Lane 2) whole cell extracts. Approximately 25 ug of lysate was loaded per lane onto a 4-20% gradient gel followed by transfer to nitrocellulose. After blocking, the membrane was incubated with the primary antibody diluted to 1 : 1000. The membrane was washed and reacted with a 1 : 10,000 dilution of IRDye® 800 Conjugated Affinity Purified Goat-anti-Rabbit IgG [H&L] MX10 (800 nm channel, green). Molecular weight estimation was made by comparison to prestained MW markers indicated at the right (Lane M, 700 nm channel, red).
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
