KLKB1 Recombinant Monoclonal Antibody

Uniprot Id

P03952

Target Species

Human

Target Name

KLKB1

Target Full Name

Plasma kallikrein

Target 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.

Target Involvement

Prekallikrein deficiency (PKK deficiency)

Target Subcellular Location

Secreted.

Target Protein Families

Peptidase S1 family, Plasma kallikrein subfamily

Target Research Area

Cell Biology

Target Synonyms

Fletcher factor; kallikrein B plasma; Kallikrein B plasma (Fletcher factor) 1; Kallikrein B; plasma 1; Kallikrein B1; Kininogenin; KLK3; KLKB1; KLKB1_HUMAN; PKK; PKKD; Plasma kallikrein; Plasma kallikrein B1; Plasma kallikrein light chain; Plasma prekallikrein; PPK; Prekallikrein

Target Background

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.
