| + | == Disease == | ||
| + | [https://www.uniprot.org/uniprot/KLKB1_HUMAN KLKB1_HUMAN] Defects in KLKB1 are the cause of prekallikrein deficiency (PKK deficiency) [MIM:[https://omim.org/entry/612423 612423]; also known as Fletcher factor deficiency. This disorder is a blood coagulation defect. | ||
| + | == Function == | ||
| + | [https://www.uniprot.org/uniprot/KLKB1_HUMAN KLKB1_HUMAN] The 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. | ||
