Kallikriens are enzymes, a serine protease, capable of peptide cleaving in the human genome. Kallikriens are responsible for various physiological functional coordination including blood pressure, semen liquefaction and skin desquamation.
Plasma related Kallikriens cleave peptides responsible for regulating blood pressure and inflammation reactions, while tissue related Kallikriens are distributed widely within the human body and are implicated in homeostatic processes. Kallikriens are implicated as biomarkers for cancer.
