摘要：
Epac proteins are activated by binding of cyclic AMP (cAMP) and act as guanine nucleotide exchange factors for Rap GTPases. They are important in the regulation of cell adhesion and insulin secretion. Here, the structure of Epac2 in a complex with cAMP and Rap1B is determined. Comparison of this activated state of the complex with the inactive one reveals the conformational changes in Epac2 induced by cAMP binding.
