PSMA (prostate-specific membrane antigen), also known as FOLH1 (folate hydrolase 1), NAALAD1 (N-acetylated-α-linked acidic dipeptidase I), GCPII (glutamate  carboxypeptidase II), FGCP (folypoly¬γ¬glutamate carboxypeptidase ), and GIG27 (cell growth-inhibiting gene 27 protein), is a tumor marker in prostate cancer.  PSMA is a single pass type II transmembrane zinc metallopeptidase that belongs to the peptidase M28 family and M28B subfamily. PSMA is most highly expressed in the nervous system, prostate, kidney, and small intestine. PSMA has folate hydrolase and N-acetylated-α-linked-acidic dipeptidase (NAALADase) activity with a preference for tri-alpha-glutamate peptides. In the intestine, PSMA hydrolyzes folylpoly¬γ-glutamates, facilitating the uptake of folate. Genetic variation in PSMA may be associated with low folate levels and consequent hyperhomocysteinemia. In the brain, PSMA modulates excitatory neurotransmission through the hydrolysis of the neuropeptide, N-aceylaspartylglutamate (NAAG), thereby releasing glutamate, another neurotransmitter. Inhibition of brain PSMA activity is considered to be a promising approach for the treatment of neurological disorders associated with glutamate excitotoxicity, such as stroke, chronic pain, and amyotrophic lateral sclerosis. PSMA also exhibits a dipeptidyl-peptidase IV (DPPIV) type activity. PSMA is involved in tumor progression In the prostate and used as an effective diagnostic and prognostic indicator of prostate cancer.

Product Details

 

Gene Symbol: PSMA; FOLH1; PSM; FGCP; FOLH; GCP2; mGCP; GCPII; NAALAD1; NAALAdase

 

NCBI Gene ID: 2346

 

Uniprot Entry: Q04609

 

Construct Details: Full length human PSMA gene (encoding UniProt #Q04609-9 or PSM-E) is subcloned into the Lentiviral expression vector pLTC with an upstream CMV promoter and with or without a selection marker, which can be used for both transient and stable expression in mammalian cells.  It can be co-transfected with the LentiPAK DNA mix (SKU# LP-001) into HEK293 cells to produce high titer lentiviral particles. Multiple choices of a stable antibiotic selection marker are available.

 

Vector Type: pLTC or pLTC-IRES-Marker (lentiviral expression vector containing a heterologous CMV promoter +/- a selection marker, see the vector map above)

 

Formulation: Supplied with 10 μg of endotoxin-free plasmid DNA at 200 ng/μl in sterile TE buffer (pH8.0)
