Recombinant Human PSA/KLK3 Protein (aa 25-261, His Tag)
Product Specifications
Background
KLK3; also known as APS; is short for Prostate-specific antigen. It is a 261 aa. protein which belongs to the peptidase S1 family and Kallikrein subfamily. This protein has 5 isforms produced by alternative splicing. It is a secreted protein and can forms a heterodimer with SERPINA5 which can inhibit its activity. KLK3 is also strongly inhibited by Zn2+; 100 times more abundant in semen than in serum. This inhibition is relieved by exposure to semenogelins; which are avid zinc binders. KLK3 can hydrolyzes semenogelin-1 thus leading to the liquefaction of the seminal coagulum.
