DEP (Dishevelled, Egl-10, and Pleckstrin) domain found in Epac-like proteins. Epac (exchange proteins directly activated by cAMP) proteins are GEFs (guanine-nucleotide-exchange factors) for the small GTPases, Rap1 and Rap2. They are directly regulated by cyclic AMP, a second messenger that plays a role in the control of diverse cellular processes, such as cell adhesion and insulin secretion. Epac-like proteins share a common domain architecture, containing RasGEF, DEP and CAP-effector (cAMP binding) domains. The DEP domain is involved in membrane localization.
