Application Abreviews Notes
WB 1/2000 - 1/10000. Detects a band of approximately 83 kDa (predicted molecular weight: 83 kDa).
  • Application notes
    Is unsuitable for IP.
  • Target

    • Function

      Polymerase that creates the 3'-poly(A) tail of mRNA's. Also required for the endoribonucleolytic cleavage reaction at some polyadenylation sites. May acquire specificity through interaction with a cleavage and polyadenylation specificity factor (CPSF) at its C-terminus.
    • Sequence similarities

      Belongs to the poly(A) polymerase family.
    • Post-translational

      Polysumoylated. Varying sumolyation depending on tissue- and cell-type. Highly sumoylated in bladder and NIH 3T3 cells. Sumoylation is required for nuclear localization and enhances PAP stability. Desumoylated by SENP1. Inhibits polymerase activity.
      Hyperphosphorylation on multiple CDK2 consensus and non-consensus sites in the C-terminal Ser/Thr-rich region represses PAP activity in late M-phase. Phosphorylation/dephosphorylation may regulate the interaction between PAP and CPSF.
      Acetylated in the C-terminus. Acetylation decreases interaction with NUDT21 and KPNB1, and inhibits nuclear localization through inhibiting binding to the importin alpha/beta complex.
    • Cellular localization

      Cytoplasm. Nucleus. The 90 kDa form is nuclear while the 100 kDa and the 106 kDa forms are both nuclear and cytoplasmic.

    Thank you for the protocol and result details. Regarding a replacement, there have not been other complaints about the antibody but not many people have purchased it. We have only the lot that you received, and I am concerned that another vial will simply give you the same result. I think a better choice for a replacement is ab126934:

    Click here (or use the following: https://www.abcam.com/index.html?datasheet=126934).

    Please let me know if you are interested in trying this. Our guarantee will also apply to this antibody, if tested on human samples in western blots. If you would rather have a refund or credit, I can issue that instead.

    Thank you for your reply. I have found your order in our system.

    Could you please let me know also the following details:

    1) What antibody dilution and incubation time was used?
    2) What was used for blocking?
    3) You reported no signal: Did you see any other bands, or was the blot completely empty?
    4) I assume the secondary antibody was HRP-conjugated, and is working well otherwise?
    5) What was your positive control antibody?

    The options weoffer are: a free of charge replacement with another PAPOLA antibody or an antibody of your choice (e.g. to a different target protein), a credit or a refund.

    Please let me know which option you would prefer.

    I look forward to hear back from you and resolve this case.
