  • FunctionThe enzyme cleaves Lys-Arg and Arg-Ser bonds. It activates, in a reciprocal reaction, factor XII after its binding to a negatively charged surface. It also releases bradykinin from HMW kininogen and may also play a role in the renin-angiotensin system by converting prorenin into renin.
  • Involvement in diseaseDefects in KLKB1 are the cause of prekallikrein deficiency (PKK deficiency) [MIM:612423]; also known as Fletcher factor deficiency. This disorder is a blood coagulation defect.
  • Sequence similaritiesBelongs to the peptidase S1 family. Plasma kallikrein subfamily.
    Contains 4 apple domains.
    Contains 1 peptidase S1 domain.
  • Cellular localizationSecreted.
  • Information by UniProt
