Description générale

Kallikrein-related peptidases belong to the family of 15 highly conserved trypsin- or chymotrypsin-like serine proteases. Plasma kallikrein (PK) is a serine protease derived from plasma prekallikrein, a zymogen found at higher levels in blood circulation. The KLKB1 gene is located on the human chromosome at 4q35.2.

Application

Kallikrein from human plasma has been used:

  • to culture human hepatocellular carcinoma cell line
  • to study its effects on the cleavage of Neisserial heparin binding antigen (NHBA) from Neisseria meningitidis
  • in peptidase inhibition assay

Actions biochimiques/physiologiques

Plasma kallikrein (PK) is involved in the synthesis of bradykinin, maintaining the blood metabolite levels and hypertension. It also participates in the activation of coagulation factor XII, which promotes inflammation and the intrinsic coagulation pathway. PK controls proteolytic cascades in the cardiovascular system like the kallikrein-kinin system, renin-angiotensin system, fibrinolytic system, and the alternative complement pathway. It is involved in the cleavage of glucagon-like peptide-1 (GLP-1) and neuropeptide Y (NPY) which suggests that plasma kallikrein may affect metabolism and diabetes.

Kallikrein-related peptidases constitute a single family of 15 (chymo)trypsin-like proteases (KLK1-15) with pleiotropic physiological roles. Aberrant regulation of KLKs has been associated with diverse diseases such as hypertension, renal dysfunction, skin disorders, inflammation, neurodegeneration, and cancer.
