Human Kininogen is a coagulation protein involved in the early stages of intrinsic pathway activation. High molecular weight kininogen deficiency (or Fitzgerald factor deficiency) can cause prolongation of the partial thromboplastin time . Human kininogen is 626 amino acids long, and has a molecular weight of 88 to 120 kD (dependent on glycosylation). High Molecular Weight Kininogen is not enzymatically active, and only functions as a cofactor for the activation of kallikrein and Hageman factor. It is also necessary for the activation of factor XI by factor XII a. Kininogen is also a precursor of bradykinin; released through positive feedback by kallikrein. As an endogenous protein substrate for tissue kallikrein, Low Molecular Weight Kininogen is involved in blood pressure regulation.
