Epac proteins are activated by binding of the second messenger cAMP and then act as guanine nucleotide exchange factors for Rap proteins. The Epac proteins are involved in the regulation of cell adhesion and insulin secretion. Here we have determined the structure of Epac2 in complex with a cAMP analogue (Sp-cAMPS) and RAP1B by X-ray crystallography and single particle electron microscopy. The structure represents the cAMP activated state of the Epac2 protein with the RAP1B protein trapped in the course of the exchange reaction. Comparison with the inactive conformation reveals that cAMP binding causes conformational changes that allow the cyclic nucleotide binding domain to swing from a position blocking the Rap binding site towards a docking site at the Ras exchange motif domain. 残り2件を表示 表示を減らす履歴 登録 2008年3月2日 登録サイト : RCSB / 処理サイト : PDBJ改定 1.0 2008年7月29日 Provider : repository / タイプ : Initial release改定 1.1 2011年7月13日 Group : Version format compliance改定 1.2 2014年2月5日 Group : Derived calculations改定 1.3 2021年8月4日 Group : Database references / Derived calculations / Refinement descriptionカテゴリ : refine / struct_ref_seq_dif / struct_siteItem : _refine.ls_percent_reflns_obs / _struct_ref_seq_dif.details ... _refine.ls_percent_reflns_obs / _struct_ref_seq_dif.details / _struct_site.pdbx_auth_asym_id / _struct_site.pdbx_auth_comp_id / _struct_site.pdbx_auth_seq_id 改定 1.4 2023年11月1日 Group : Data collection / Database references / Refinement descriptionカテゴリ : chem_comp_atom / chem_comp_bond ... chem_comp_atom / chem_comp_bond / database_2 / pdbx_initial_refinement_model Item : _database_2.pdbx_DOI / _database_2.pdbx_database_accession
