Background Information

Kininogens are inhibitors of thiol proteases. Kininogen 1 plays important role in Kinin-kallikrein system. This KNG1 gene contains 10 exons and encodes two proteins through alternative splicing: high molecular weight kininogen (HMWK) (72kDa) and low molecular weight kininogen (LMWK) (48kDa) (PMID: 37442062). HMWK is produced by the liver together with prekallikrein. It acts mainly as a cofactor on coagulation and inflammation, and has no intrinsic catalytic activity. LMWK is produced locally by numerous tissues, and secreted together with tissue kallikrein. 11926-1-AP was generated against N-terminal 300 aa of HMW kininogen. It can bind both HMW and LMW kiniogen.
