Details
Function: (1) Kininogens are inhibitors of thiol proteases; (2) HMW-kininogen plays an important role in blood coagulation by helping to position optimally prekallikrein and factor XI next to factor XII; (3) HMW-kininogen inhibits the thrombin- and plasmin-induced aggregation of thrombocytes; (4) the active peptide bradykinin that is released from HMW-kininogen shows a variety of physiological effects: (4A) influence in smooth muscle contraction, (4B) induction of hypotension, (4C) natriuresis and diuresis, (4D) decrease in blood glucose level, (4E) it is a mediator of inflammation and causes (4E1) increase in vascular permeability, (4E2) stimulation of nociceptors (4E3) release of other mediators of inflammation (e.g. prostaglandins), (4F) it has a cardioprotective effect (directly via bradykinin action, indirectly via endothelium-derived relaxing factor action); (5) LMW-kininogen inhibits the aggregation of thrombocytes; (6) LMW-kininogen is in contrast to HMW-kininogen not involved in blood clotting.

Post-translational modification: Bradykinin is released from kininogen by plasma kallikrein. Phosphorylation sites are present in the extracelllular medium (By similarity).

Similarity: Contains 3 cystatin domains.

Subcellular location: Secreted, extracellular space.

Tissue specificity: Plasma.

Alternative products: Event=Alternative splicing; Named isoforms=2; Name=HMW; IsoId=P08934-1; Sequence=Displayed; Name=LMW; IsoId=P08934-2; Sequence=VSP_001265, VSP_001266.

Sequence length: 331 AA.
