Target

  • Function

    Has both folate hydrolase and N-acetylated-alpha-linked-acidic dipeptidase (NAALADase) activity. Has a preference for tri-alpha-glutamate peptides. In the intestine, required for the uptake of folate. In the brain, modulates excitatory neurotransmission through the hydrolysis of the neuropeptide, N-aceylaspartylglutamate (NAAG), thereby releasing glutamate. Isoform PSM-4 and isoform PSM-5 would appear to be physiologically irrelevant. Involved in prostate tumor progression.
    Also exhibits a dipeptidyl-peptidase IV type activity. In vitro, cleaves Gly-Pro-AMC.
  • Tissue specificity

    Highly expressed in prostate epithelium. Detected in urinary bladder, kidney, testis, ovary, fallopian tube, breast, adrenal gland, liver, esophagus, stomach, small intestine, colon and brain (at protein level). Detected in the small intestine, brain, kidney, liver, spleen, colon, trachea, spinal cord and the capillary endothelium of a variety of tumors. Expressed specifically in jejunum brush border membranes. In the brain, highly expressed in the ventral striatum and brain stem. Also expressed in fetal liver and kidney. Isoform PSMA' is the most abundant form in normal prostate. Isoform PSMA-1 is the most abundant form in primary prostate tumors. Isoform PSMA-2 is also found in normal prostate as well as in brain and liver. Isoform PSMA-9 is specifically expressed in prostate cancer.
  • Sequence similarities

    Belongs to the peptidase M28 family. M28B subfamily.
  • Domain

    The NAALADase activity is found in the central region, the dipeptidyl peptidase IV type activity in the C-terminal.
  • Post-translational
    modifications

    The first two amino acids at the N-terminus of isoform PSMA' appear to be cleaved by limited proteolysis.
    The N-terminus is blocked.
  • Cellular localization

    Cytoplasm and Cell membrane.

    Answer

    Thank you for contacting us.

    Unfortunately ab66912 is not tissue specific. I did however search our catalog and have found 2 products which may suit your needs. When searching for prostate cancer specific PSMA antibodies I found that the isoform expressed in normal tissue is PSMA* whereas isoforms PSMA-1 and PSMA-9 were most abundant inprostate cancer tissues oris specifically expressed in prostate cancer respectively. Therefore a search for an antibody against the N-terminal region seems the best chance for finding cancer tissue specificity as PSMA* is missing aa1-57 (http://www.uniprot.org/uniprot/Q04609).

    While we do not have data to show that the following antibodies will stain only prostate cancer tissues the immunogen regions from which they were created do match the isoforms most abundant in primary prostate tumors and not with the form found in normal prostate.

    Ab76104: The immunogen is located within aa1-25. As such this product will only recognize isoform 1 and isoform 8.The product page for ab76104 is at:https://www.abcam.com/PSMA-antibody-EP3253-ab76104.html

    Ab41034: The immunogen region is from aa43- aa60 so this is likely not to recognize PSMA* but will recognizePSMA-1 and PSMA-9. The product page is located at this address:https://www.abcam.com/PSMA-antibody-ab41034.html

    Question

    I am currently trying to identify the levels of PSMA expression in human cell and tumor lysates by western blot analysis in both reducing and native conditions and was wondering if you have a primary antibody that would be useful in both of these applications? I have been using your YPSMA antibody but have found differing expression levels for the same cells under reducing and native conditions and would like to optimize this assay as much as possible.

    Any information you can give would be greatly appreciated,

    Asked on Mar 28 2012

    Answer

    Thank you for contacting us.

    We do not have anti PSMA antibody that would detect both the native as well as reduced form of protein. We however have more than 20 products that are used under reducing conditions and gave best results. Taking ion consideration the current data we have, It is hard to tell which antibody is suitable for native protein, theoretically every antibody should detect however there are certain antibodies that works well under denatured and reduced conditions rather than native.

    I am sorry we are not aware about our PSMA antibodies for their use under native conditions. This has to determined by the end user.

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