The PSMA protein is a multifunctional enzyme with folate hydrolase and NAALADase activities and a preference for tri-alpha-glutamic acid peptides. It absorbs folate in the intestines, aids in important metabolic processes, and modulates excitatory neurotransmission in the brain by hydrolyzing NAAG to release glutamate. PSMA Protein, Mouse (Biotinylated, HEK293, His) is the recombinant mouse-derived PSMA protein, expressed by HEK293 , with N-His labeled tag.
