Prekallikrein to kallikrein
Did you know?
Prekallikrein (PK), also known as Fletcher factor, is an 85,000 Mr serine protease that complexes with high-molecular-weight kininogen. PK is the precursor of plasma kallikrein, which is a serine protease that activates kinins. PK is cleaved to produce kallikrein by activated Factor XII (Hageman factor). See more Prekallikrein is homologous to factor XI, and similarly consists of four apple domains and a fifth, catalytic serine protease domain. The four apple domains create a disk-like platform around the base of the catalytic domain. However, … See more PK was initially described by Hathaway et al. in 1965 after encountering a Kentucky family who exhibited strikingly abnormal APTT results, but … See more Hereditary deficiencies in PK are very rare. They can cause a prolonged APTT, which can be corrected by incubation of the patient’s plasma. Deficiencies in PK can also be acquired due to some disease states, such as angioedema, … See more The KLKB1 gene encoding plasma kallikrein is located on chromosome 4q34-35. It is synthesised as an inactive precursor, prekallikrein, which must undergo proteolytic processing to become activated. This is facilitated by factor XII, PRCP or other stimuli. Plasma kallikrein liberates kinins (bradykinin and kallidin) from the kininogens, p…
