Human Kallikrein 4 / KLK-4 Protein, His Tag (active enzyme, HPL

Kallikrein-related peptidase 4 (KLK4) is a secreted serine protease primarily expressed in teeth, prostate, and other tissues. It plays a key role in enamel maturation by degrading enamel matrix proteins. Dysregulation of KLK4 is linked to dental defects, cancer progression, and other pathologies, making it a biomarker and potential therapeutic target.
