PPACKII is a specific and irreversible inhibitor of glandular and plasma kallikreins [1].
Human tissue kallikreins (hKs) are a class of secreted serine proteases that involved in the release of vasodepressor peptides or kinins from a plasma substrate. Kallikrein has diverse expression patterns and physiological roles. Kallikrein has been primarily known as cancer biomarkers. Kallikrein has been implicated in many cancer-related processes, such as cell-growth regulation, angiogenesis, invasion and metastasis. Kallikrein could promote or inhibit neoplastic progression individually and/or with the interaction in cascades with other hKs and proteases [2].
PPACKII prevented apolipoprotein proteolysis in dextran sulfate-precipitated human plasma LDL and inhibited serum atrial natriuretic peptide cleavage at micromolar concentrations [1]. It has been reported that PPACKII inactivated the amidolytic activity of native human Hageman Factor (Factor XII) at 5.3 μM [3].
