Kininogen 1
Kininogen-1 (KNG1), also known as alpha-2-thiol proteinase inhibitor, Williams-Fitzgerald-Flaujeac factor or the HMWK-kallikrein factor is a protein[5] that in humans is encoded by the KNG1 gene.[6][7] Kininogen-1 is the precursor protein to high-molecular-weight kininogen (HMWK), low-molecular-weight kininogen (LMWK), and bradykinin.[5]

Expression
The KNG1 gene uses alternative splicing to generate two different proteins: high-molecular-weight kininogen (HMWK) and low-molecular-weight kininogen (LMWK). HMWK in turn is cleaved by the enzyme kallikrein to produce bradykinin.
- KNG1 gene → low-molecular-weight kininogen (LMWK) protein (contains 427 amino acids) or high-molecular-weight kininogen (HMWK) protein (644 amino acids)
- HMWK protein → bradykinin peptide (9 amino acids)
Function
HMWK is essential for blood coagulation and assembly of the kallikrein-kinin system. Also, bradykinin, a peptide causing numerous physiological effects, is released from HMWK. In contrast to HMWK, LMWK is not involved in blood coagulation.[6]
Kininogen-1 is a constituent of the blood coagulation system as well as the kinin-kallikrein system.
