  • 功能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.
  • 组织特异性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.
  • 序列相似性Belongs to the peptidase M28 family. M28B subfamily.
  • 结构域The NAALADase activity is found in the central region, the dipeptidyl peptidase IV type activity in the C-terminal.
  • 翻译后修饰The first two amino acids at the N-terminus of isoform PSMA' appear to be cleaved by limited proteolysis.
    The N-terminus is blocked.

Product Wall

I can confirm that there is only one Phycoerythrin molecule conjugated to one antibody molecule in this product (ab77228).

For western blotting with GCP-05 with LnCaP cells, one just needs a standard whole cell extract. There is no LnCaP-focused procedure that I am aware of.

Regarding references, all publications we are aware of that have used this anti...
