C2 domains (C2s) are regulatory protein modules identified in eukaryotic proteins targeted to cell membranes. C2s were initially characterized as independently folded Ca2+-dependent phospholipids binding domains; however, later studies have shown that C2s have evolutionarily diverged into Ca2+-dependent and Ca2+-independent forms. These forms interact and regulate their affinity to diverse lipid species using different binding mechanisms. In this protocol we describe a biochemical approach to produce, purify, and solubilize functional C2 domains bound to GST for the identification of their putative Ca2+-dependent and Ca2+-independent lipid-binding partners.
