  • Function
    This protein is an 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.
  • Sequence similarities
    Belongs to the PCNA family.
  • Post-translational
    Upon methyl methanesulfonate-induced DNA damage, mono-ubiquitinated by the UBE2B-RAD18 complex on Lys-164. This induces non-canonical polyubiquitination on Lys-164 through 'Lys-63' linkage of ubiquitin moieties by the E2 complex UBE2N-UBE2V2 and the E3 ligases, HLTF, RNF8 and SHPRH, which is required for DNA repair. 'Lys-63' polyubiquitination prevents genomic instability on DNA damage. Monoubiquitination at Lys-164 also takes place in undamaged proliferating cells, and is mediated by the DCX(DTL) complex, leading to enhance PCNA-dependent translesion DNA synthesis.
    Acetylated in response to UV irradiation. Acetylation disrupts interaction with NUDT15 and promotes degradation.
  • Cellular localization
    Nucleus. Forms nuclear foci representing sites of ongoing DNA replication and vary in morphology and number during S phase. Together with APEX2, is redistributed in discrete nuclear foci in presence of oxidative DNA damaging agents.

Customer reviews and Q&As

I am sorry if there was mis-communication. The customer, according to your previous e-mail, asked for a quote for PCNA antibodies which are known to be reactive with zebrafish. The two I mentioned in my previous e-mail are: ab29 - 100µg for $35...

I am sorry to read that your customer is still having difficulty with ab53048. If I understand you correctly, the customer wants to know which antibodies we recommend for detecting PCNA in zebrafish samples. We have two: ab29 - 100µg for...

Thank you for the protocol details and the image. I assume the customer is expecting to see more PCNA expression in a subset of cells. It is difficult, with this image, for me to identify specific regions of the embryo but I think there will be...

Thank you for bringing this to our attention. The antibodies we offer are generally stable at 4ºC for several weeks, if not months. The recommendation for storage at -20ºC refers to long-term storage (beyond a few weeks), so it is unlikely that the del...
