概述
Kallikreins are members of the peptidase S1 family,which is a highly conserved serine proteases family.Fifteen kallikreins who seen coding genes are located in a cluster on chromosome 19.Human kallikrein1(KLK1),also known as tissue kallikrein,is functionally conserved in its capacity to cleave the low molecular weight kininogen to release the vasoactive peptide,Lys-bradykinin which plays a role in regulating vasodilation,blood pressure reduction,smooth muscle relaxation and contraction,pain induction and inflammation.Additionally,it have been reported,and growing evidence suggests that many kallikreins are implicated in carcinogens is and some have potential as novel cancer and other disease biomakers.
