Uniprot ID: KNG1_HUMAN
Immunogen Region: Gln 19-Ser 427
Immunogen: Recombinant Human Kininogen-1/KNG1 Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Gln 19-Ser 427) of human Kininogen-1 (Accession #NP_000884) fused with a 6×His tag at the C-terminus.
Post Translational Modifications Bradykinin: Bradykinin is inactivated by ACE, which removes the dipeptide Arg-Phe from its C-terminus. Bradykinin is released from kininogen by plasma kallikrein. Hydroxylation of Pro-383 occurs prior to the release of bradykinin. Phosphorylated by FAM20C in the extracellular medium. N- and O-glycosylated. O-glycosylated with core 1 or possibly core 8 glycans. (Microbial infection) Bradykinin is generated upon proteolytic cleavage by S.pyogenes SpeB to produce hypotension during septic shock.
Function 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.HMW-kininogen inhibits the thrombin- and plasmin-induced aggregation of thrombocytes. LMW-kininogen inhibits the aggregation of thrombocytes. LMW-kininogen is in contrast to HMW-kininogen not involved in blood clotting. Bradykinin: The active peptide bradykinin is a potent vasodilatator that is released from HMW-kininogen shows a variety of physiological effects: (A) influence in smooth muscle contraction, (B) induction of hypotension, (C) natriuresis and diuresis, (D) decrease in blood glucose level, (E) it is a mediator of inflammation and causes (E1) increase in vascular permeability, (E2) stimulation of nociceptors (4E3) release of other mediators of inflammation (e.g. prostaglandins), (F) it has a cardioprotective effect (directly via bradykinin action, indirectly via endothelium-derived relaxing factor action).
