Entrez Gene summary for KLKB1 Gene:
Plasma prekallikrein is a glycoprotein that participates in the surface-dependent activation of blood coagulation,
fibrinolysis, kinin generation and inflammation. It is synthesized in the liver and secreted into the blood as a
single polypeptide chain. Plasma prekallikrein is converted to plasma kallikrein by factor XIIa by the cleavage
of an internal Arg-Ile bond. Plasma kallikrein therefore is composed of a heavy chain and a light chain held
together by a disulphide bond. The heavy chain originates from the amino-terminal end of the zymogen and contains
4 tandem repeats of 90 or 91 amino acids. Each repeat harbors a novel structure called the apple domain. The
heavy chain is required for the surface-dependent pro-coagulant activity of plasma kallikrein. The light chain
contains the active site or catalytic domain of the enzyme and is homologous to the trypsin family of serine
proteases. Plasma prekallikrein deficiency causes a prolonged activated partial thromboplastin time in patients.

GeneCards Summary for KLKB1 Gene: 
KLKB1 (kallikrein B, plasma (Fletcher factor) 1) is a protein-coding gene. Diseases associated with KLKB1 include fletcher factor deficiency, and malignant essential hypertension, and among its related super-pathways are Formation of Fibrin Clot (Clotting Cascade) and Collagen biosynthesis and modifying enzymes. GO annotations related to this gene include protein binding and serine-type endopeptidase activity. An important paralog of this gene is TMPRSS11D.

UniProtKB/Swiss-Prot: KLKB1_HUMAN, P03952
Function: 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
