Kalikrein

Kalikreini su podgrupa serinskih proteaza, enzima koji imaju sposobnost razlaganja peptidnih veza u proteinima. Kod ljudi, kalikrein plazme[1][2][3][4][5] (KLKB1) nema poznatih homologa, dok tkivne kalikreinu srodne peptidaze (KLKs) kodiraju familiju od petnaest blisko srodnih serinskih proteaza. Ti geni su locirani na hromozomu 19q13, i formiraju najveći kluster susednih proteaza u ljudskom genomu. Kalikreini su odgovorni za koordinaciju raznih fizioloških funkcija uključujući krvni pritisak, utečnjavanje semena i deskvamaciju kože.
