KKI-5 (TFA) is a specific inhibitor of tissue kallikrein. KKI-5 (TFA) can attenuate breast cancer cell invasion[1].
The KKI-5 Peptide corresponds to aa386-391 of bovine kininogen-1 that encompasses the aa388-389 kallikrein proteolytic site. The synthetic KKI-5 can attenuate breast cancer cell invasion, therefore it is investigated for its role in invasion and metastasis of cancer cells[1].
