Structure, function, and regulation of the enzyme activity of prostate-specific antigen
Prostate-specific antigen (PSA) and human glandular kallikrein 1 (hGK-1) are structurally similar products of the human glandular kallikrein gene locus on chromosome 19 that become selectively expressed by human prostate tissue. PSA is one of the most abundant prostate-derived proteins in the seminal fluid. The mature form of PSA, a single-chain glycoprotein of 237 amino acids, is a serine proteas
