Swiss-port # P07288 Human Prostate-specific antigen

Gene Symbol KLK3
Gene Full Name kallikrein-related peptidase 3
Background Free prostate specific antigen (fPSA) is the unbounded form of PSA. Study has shown that low percentage of fPSA in total PSA (tPSA) is associated with high risk of prostate cancer. Using percentage of fPSA in tPSA can enhance the predication of prostate cancer and avoid unnecessary biopsies in prostate screen.
Function Hydrolyzes semenogelin-1 thus leading to the liquefaction of the seminal coagulum. [UniProt]
