General description

Native, single chain, high molecular weight Kininogen from human plasma. Non-enzymatic cofactor of the contact activation system. Links prekallikrein to negatively charged surfaces, thereby allowing activation to kallikrein by surface-bound Factor a-XIIa. Also circulates in plasma in complex with Factor XI, that may play a role in the activation of Factor XI to Factor XIa by Factor α-XIIa. Serves as a source of bradykinin, a potent vasoactive peptide important in hypotension studies.

Inter-α-inhibitor heavy chain 4 (ITIH4) is a poorly characterized plasma protein that is proteolytically processed in multiple pathological conditions. However, no biological function of ITIH4 has been identified. Here, we show that ITIH4 is cleaved by several human proteases within
