Kallikrein Inhibitor is a synthetic peptide. The synthetic kallikrein inhibitor can attenuate breast cancer cell invasion.
The Kallikrein Inhibitor Peptide corresponds to aa386-391 of bovine kininogen-1 that encompasses the aa388-389 kallikrein proteolytic site. The synthetic kallikrein inhibitor can attenuate breast cancer cell invasion, therefore it is investigated for its role in invasion and metastasis of cancer cells.
