Anti-Kallikrein-1/KLK1 Antibody, clone 11C7.1 clone 11C7.1, from mouse

Kallikrein-1 (EC:3.4.21.35; UniProt P06870; also known as Glandular kallikrein 1, hK1, Kallikrein serine protease 1, Kidney/pancreas/salivary gland kallikrein, Renal/pancreas/salivary kallikrein 1, Tissue kallikrein) is encoded by the KLK1 (also known as KLKR) gene (Gene ID 3816) in human. Kallikrein-1 is a member of the kallikrein subfamily of serine proteases, members of which are involved in diverse physiological functions and many are used clinically as biomarkers for cancer. Kallikrein-1 is initially produced as a preproprotein with a signal (aa 1-18) and a propeptide (aa 19-24), cleavage of which releases the mature protein (aa 25-262). Kallikrein-1 is the major kallikrein expressed in the kidney, where it generates kinins (e.g. lysyl-bradykinin and bradykinin) and plays role in kidney function and blood pressure regulation through vasodilatory and natriuretic effects. Decreased kidney Kallikrein-1 level is reported in experimental settings of hypertension, diabetic nephropathy, high salt- and aminoglycoside-induced kidney injury.
