84-4987-06　KLKB1 (Plasma Kallikrein, Kallikrein B, Plasma (Fletcher Factor) 1) 100ul　484417

特徴

• 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 prekallikrein deficiency causes a prolonged activated partial thromboplastin time in patients.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 91aa.
• 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.
• Applications:Suitable for use in Western Blot.
