  • 機能

    Binds the poly(A) tail of mRNA, including that of its own transcript. May be involved in cytoplasmic regulatory processes of mRNA metabolism such as pre-mRNA splicing. Its function in translational initiation regulation can either be enhanced by PAIP1 or repressed by PAIP2. Can probably bind to cytoplasmic RNA sequences other than poly(A) in vivo. Involved in translationally coupled mRNA turnover. Implicated with other RNA-binding proteins in the cytoplasmic deadenylation/translational and decay interplay of the FOS mRNA mediated by the major coding-region determinant of instability (mCRD) domain. Involved in regulation of nonsense-mediated decay (NMD) of mRNAs containing premature stop codons; for the recognition of premature termination codons (PTC) and initiation of NMD a competitive interaction between UPF1 and PABPC1 with the ribosome-bound release factors is proposed. By binding to long poly(A) tails, may protect them from uridylation by ZCCHC6/ZCCHC11 and hence contribute to mRNA stability (PubMed:25480299). Positively regulates the replication of dengue virus (DENV) (PubMed:26735137).

      PABP was immunoprecipitated using 0.5mg Hela whole cell extract, 5µg of Mouse monoclonal to PABP (ab6125) and 50µl of protein G magnetic beads (+). No antibody was added to the control (-).
      The antibody was incubated under agitation with Protein G beads for 10min, Hela whole cell extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.
      Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70oC; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab6125.

The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab6125, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-mouse IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

    Question

    Dear concerning,
    A user would like to use Anti-PABP antibody [10E10] (ab6125) on follicular fluids by ELISA. Could you please suggest a dilution rate for the antibody to use ELISA? Additionally, is PABP peptide (ab23710) suitable to use with PABP antibody [10E10] (ab6125) as standard?

    Read More
    Answer

    Thank you for contacting us.

    There is not a specific concentration recommended for the use of this antibody in ELISA. Optimisation is required with different dilutions in order to assess the best one for your particular conditions. We can however suggest a good starting point to begin with, for purified antibodies tested in ELISA this corresponds to 0.1ug/ml.

    Regarding the suitability of ab23710 to be used as standard with the antibody, I am afraid I cannot assure the antibody will recognize it, as its epitope has not been mapped, and we have not tested this pair in house.

    However, the peptide ab23710 has been used to raise another Anti-PABP antibody:

    I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

    Question

    What is the isotype of this antibody? It's listed as IgG2b but other sources indicate this clone is an IgG1.

    Read More
    Answer

    Thank you again for your calls and for your patience while we have looked into your enquiry. I apologize again for the delay in getting this information for you.

    My contact at the lab confirms that this antibody has an IgG2b isotype. I've looked online and there are other antibodies with the 10E10 clone number (though one is to a different protein target, Raptor). I'm not sure how to explain the discrepancy with the PABP antibody listed as an IgG1 isotype from other vendors, though most companies seem tolist this as an IgG2b clone.

    I am sorry that we don'thavemore of an explain regarding this discrepancy, but if you have any further questions or if there is anything else that we can do for you, please let me know and I'll be happy to help.

    Answer

    Thank you for your calls last week and earlier this week, and I apologize for the delay getting this information for you.

    I've called over to the lab, andmy colleaguewho has more information about ab6125 has been out of the office. We should have some answers early next week.

    I apologize again that this is taking so long, and we appreciate your patience. Please let me know if you have any questions or need anything else in the meantime.

    Question

    I have purchased the anti-PABP antibody (ab6125) and used it successfully in western blot experiments. Recently I have attempted to use it in antibody inhibition experiments with RNA and have found that the RNA is being degraded during the experiment. I was under the impression that these antibodies were highly purified and therefore should be free of ribonucleases. It would be greatly appreciated if you have knowledge about the purity of the antibodies generated (if it is lot dependent) and if abcam or any other company guarantees their antibodies to be nuclease free.

    Read More
    Answer

    Thank you for your enquiry. I have received information from our laboratory. The purification steps are not done aseptically (it's impossible) and so whilst I guess there could be some bacterially derived endonuclease, I think it unlikely as all our columns are stored in ethanol and all the tubing etc washed extensively before each run. Moreover, even if there were any endonucleases present, I would be surprised if they bound non specifically to protein G and so I wouldn't expect to see them in the end product. This is substantiated by the fact that we don't see any low (12-14Kd) MW bands in the preps when we run SDS-PAGE gels. Whilst we filter sterilize the preps prior to despatch, I guess if the antibody has subsequently been handled non-aseptically at any point, this could introduce bacteria which could produce endonuclease, however I think it unlikely. I hope this information will be useful to you. Should you require any further information, please do not hesitate to contact me.

    could you please send me the sequence of PABP that is recognized by the antibody 10E10.

    Read More
    Answer

    At Abcam, we have one centralized database to hold all of our product information, so that everything we know about this antibody is on this datasheet. We are unable to supply the epitope sequence as this is deemed commercially sensitive information. However it may be of help to you to view the references cited at the base of the data sheet. If you need any further information please get in touch once again.
