Together with endopeptidase inhibitor, protease, and signaling receptor binding activities, the Kininogen-1 protein is predicted to play a critical role in antimicrobial response, coagulation regulation, and control of endopeptidase activity.Kininogen-1 is located in the collagen-containing matrix and shows biased expression, particularly in the liver at embryonic (E18) and adult stages (RPKM 646.0 and 179.1).Kininogen-1 Protein, Mouse (HEK293, His) is the recombinant mouse-derived Kininogen-1 protein, expressed by HEK293 , with C-His labeled tag.
