Predicted to enable cysteine-type endopeptidase inhibitor activity and signaling receptor binding activity. Predicted to be involved in several processes, including blood coagulation; negative regulation of blood coagulation; and negative regulation of endopeptidase activity. Predicted to be located in extracellular space. Used to study abdominal aortic aneurysm. Human ortholog(s) of this gene implicated in high molecular weight kininogen deficiency. Orthologous to human KNG1 (kininogen 1). [provided by Alliance of Genome Resources, Apr 2022]
