This gene encodes a glycoprotein that participates in the surface-dependent activation of blood coagulation, fibrinolysis, kinin generation and inflammation. The encoded preproprotein present in plasma as a non-covalent complex with high molecular weight kininogen undergoes proteolytic processing mediated by activated coagulation factor XII to generate a disulfide-linked, heterodimeric serine protease comprised of heavy and light chains. Certain mutations in this gene cause prekallikrein deficiency. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jan 2016]

KLKB1 (Kallikrein B1) is a Protein Coding gene. Diseases associated with KLKB1 include Prekallikrein Deficiency and Malignant Essential Hypertension. Among its related pathways are Complement and coagulation cascades and Formation of Fibrin Clot (Clotting Cascade). Gene Ontology (GO) annotations related to this gene include serine-type endopeptidase activity and heme binding. An important paralog of this gene is F11.
UniProtKB/Swiss-Prot for KLKB1 Gene
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.
