Background: Serpin A4/Kallistatin

Serpin A4 is a member of the Serpin superfamily of the serine protease inhibitors (1). Known also as Kallistatin or proteinase inhibitor 4, Serpin A4 has been shown to function as a specific inhibitor of tissue kallikrein and as an inhibitor of angiogenesis and tumor growth (2, 3).
