Kininogens are inhibitors of thiol proteases. HMW-kininogen plays an important role in blood coagulation by helping to position optimally prekallikrein and factor XI next to factor XII and inhibits the thrombin- and plasmin-induced aggregation of thrombocytes. The active peptide bradykinin that is released from HMW-kininogen shows a variety of physiological effects such as influence in smooth muscle contraction, induction of hypotension, natriuresis and diuresis, etc. Alias Symbols: BDK, KNG Protein Interaction Partner: Ance, ECE1, COPS6, RXFP4, CPN1, F11, HABP2, CTSK, PREP, MEP1A, ITGB2, GP1BA, KLKB1, KNG1, VTN, THBS1, F2, PLAUR, PLG, KLK1, KRT1, FTL, ELANE, CD93, CTSL, CTSS, CTSG, CAPN2, CAPN1, AGT, APP, Protein Size: 391
