PSMA

Prostate-specific membrane antigen

PSMA is a transmembrane protein that anchores to the cell membrane through its transmembrane region and is mainly expressed in prostate epithelial cells but also exists in other tissues. PSMA exhibits glutamate-preferring carboxypeptidase activity that hydrolyzes polyglutamylated folic acid to release folic acid monomers. PSMA mediates the endocytosis on the cell surface. PSMA acts as an angiogenesis marker in cancer cells. PSMA can be used as a diagnostic marker for prostate cancer, and for detection of invasiveness and metastatic ability of the tumor[1].
