Secondary Information

Presence in other biological fluids/tissue/cells tears, CSF, saliva
Protein Function accelerate the activation of factor XII, prekallikrein, and factor XI as cofactor; Fragment 1.2 has also been shown to be a potent inhibitor of the contact activation of factor XII;
Biochemical Properties rich in basic amino acid residue, containing 22 histidines, 13 lysines, and 3 arginines in a total of 110 residues; basic proteins such as protamine, lysozyme, and synthetic polylysine inhibit the activation for factor XII by a negatively charged surface
Significance in milk maintaining the bone strength and content of hydroxyproline
PTMs Bovine fragment 1.2 of HMW kininogen has four oligosaccharide chains that attached to serine and threonine residues. The residues with oligosaccharide chains are S10, T10, T12, S18 from the amino-terminal of the fragment 1.2;
