Kallikrein 2 (KLK2) is a secreted serine protease that is highly expressed in the human prostate gland. It is also known as the prostate­specific glandular kallikrein. The enzyme is highly specific for cleavage after arginine residues. KLK2 is able to activate the urokinase­type plasminogen activator. KLK2 is inhibited by serpins such as protein C inhibitor, antichymotrypsin, and plasminogen activator inhibitor 1. KLK2 is structurally related to KLK3, the prostate­specific antigen (PSA). Like PSA, KLK2 is considered to be a biomarker for prostate cancer.
