PSMA
Also known as: Prostate Specific Membrane Antigen
Use
Prostate specific membrane antigen (PSMA) is a 750 amino acid type II membrane glycoprotein with folate hydrolase and neuropeptidase activity. PSMA is expressed in normal and malignant prostatic epithelium and in a subset of non‑prostatic tissues. In prostate cancer, PSMA expression has been shown to correlate with disease progression, with the highest levels expressed in hormone‑refractory and metastatic disease. PSMA expression has also been reported on the neovasculature of a variety of non‑prostatic solid tumors.
