|Other Names||Glutamate carboxypeptidase 2, Cell growth-inhibiting gene 27 protein, Folate hydrolase 1, Folylpoly-gamma-glutamate carboxypeptidase, FGCP, Glutamate carboxypeptidase II, GCPII, Membrane glutamate carboxypeptidase, mGCP, N-acetylated-alpha-linked acidic dipeptidase I, NAALADase I, Prostate-specific membrane antigen, PSM, PSMA, Pteroylpoly-gamma-glutamate carboxypeptidase, FOLH1, FOLH, NAALAD1, PSM, PSMA|
|Target/Specificity||The synthetic peptide sequence used to generate the antibody AP13707a was selected from the N-term region of FOLH1. A 10 to 100 fold molar excess to antibody is recommended. Precise conditions should be optimized for a particular assay.|
|Format||Synthetic peptide was lyophilized with 100% acetonitrile and is supplied as a powder. Reconstitute with 0.1 ml DI water for a final concentration of 1 mg/ml.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C.|
|Precautions||This product is for research use only. Not for use in diagnostic or therapeutic procedures.|
|Synonyms||FOLH, NAALAD1, PSM, PSMA|
|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. Involved in prostate tumor progression.|
|Cellular Location||Cell membrane; Single-pass type II membrane protein|
|Tissue Location||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-3 is also found in normal prostate as well as in brain and liver. Isoform PSMA-9 is specifically expressed in prostate cancer|

This gene encodes a type II transmembrane glycoproteinbelonging to the M28 peptidase family. The protein acts as aglutamate carboxypeptidase on different alternative substrates,including the nutrient folate and the neuropeptideN-acetyl-l-aspartyl-l-glutamate and is expressed in a number oftissues such as prostate, central and peripheral nervous system andkidney. A mutation in this gene may be associated with impairedintestinal absorption of dietary folates, resulting in low bloodfolate levels and consequent hyperhomocysteinemia. Expression ofthis protein in the brain may be involved in a number ofpathological conditions associated with glutamate excitotoxicity.In the prostate the protein is up-regulated in cancerous cells andis used as an effective diagnostic and prognostic indicator ofprostate cancer. This gene likely arose from a duplication event ofa nearby chromosomal region. Alternative splicing gives rise tomultiple transcript variants encoding several different isoforms.
