Kallistatin also known as PI-4 is a serine proteinase inhibitor with a mass of approximately 52 kDa. You find it mainly in the liver as part of the serpin superfamily. This protein acts mechanically by inhibiting the tissue kallikrein-kinin system which involves proteolytic processes that regulate vascular homeostasis and blood pressure. In addition to the liver kallistatin is expressed in endothelial cells and various human tissues.
Biological function summary
Kallistatin participates in inhibiting angiogenesis and inflammation impacting cellular behavior and responses. As a serpin it functions uniquely in forming stable complexes with target enzymes like tissue kallikrein. Through this mechanism kallistatin contributes to maintaining vascular integrity and preventing excessive vascular growth or inflammation that could lead to pathology.
Pathways
The inhibitory effects of kallistatin integrate into the kallikrein-kinin system and the renin-angiotensin system. In the kallikrein-kinin system kallistatin regulates processes involving vascular tone and fluid balance. It interacts with proteins such as bradykinin mediating inflammatory responses and endothelial cell function through these key pathways.
Researchers link kallistatin with conditions like hypertension and cancer. Its role in inhibiting angiogenesis and inflammation helps understand its protective effects against tumor growth and metastasis. In hypertension kallistatin's relationship with the renin-angiotensin system connects it to other proteins like angiotensin II influencing blood pressure regulation and vascular health.
