Kallistatin consists of three folded ß segments and eight helical structures and contains two functional domains, an active site and a heparin-binding site.

Kallistatin signals through several receptors, including integrin ß3, lipoprotein receptor-related protein 6 ( LRP6 ), nucleolin, and Krüppel-like factor 4 ( KLF4 ).^[5][6]
