引用ジャーナル : Cell Rep / 年 : 2019タイトル : The Structural Basis for the Binding of Repaglinide to the Pancreatic K Channel.著者 : Dian Ding / Mengmeng Wang / Jing-Xiang Wu / Yunlu Kang / Lei Chen / 要旨 : Repaglinide (RPG) is a short-acting insulin secretagogue widely prescribed for the treatment of type 2 diabetes. It boosts insulin secretion by inhibiting the pancreatic ATP-sensitive potassium ... Repaglinide (RPG) is a short-acting insulin secretagogue widely prescribed for the treatment of type 2 diabetes. It boosts insulin secretion by inhibiting the pancreatic ATP-sensitive potassium channel (K). However, the mechanisms by which RPG binds to the K channel are poorly understood. Here, we describe two cryo-EM structures: the pancreatic K channel in complex with inhibitory RPG and adenosine-5'-(γ-thio)-triphosphate (ATPγS) at 3.3 Å and a medium-resolution structure of a RPG-bound mini SUR1 protein in which the N terminus of the inward-rectifying potassium channel 6.1 (Kir6.1) is fused to the ABC transporter module of the sulfonylurea receptor 1 (SUR1). These structures reveal the binding site of RPG in the SUR1 subunit. Furthermore, the high-resolution structure reveals the complex architecture of the ATP binding site, which is formed by both Kir6.2 and SUR1 subunits, and the domain-domain interaction interfaces. 履歴 登録 2019年1月25日 登録サイト : PDBJ / 処理サイト : PDBJ改定 1.0 2019年5月22日 Provider : repository / タイプ : Initial release改定 1.1 2019年11月6日 Group : Data collection / Other / カテゴリ : atom_sites / cellItem : _atom_sites.fract_transf_matrix[1][1] / _atom_sites.fract_transf_matrix[2][2] ... _atom_sites.fract_transf_matrix[1][1] / _atom_sites.fract_transf_matrix[2][2] / _atom_sites.fract_transf_matrix[3][3] / _cell.Z_PDB 改定 2.0 2021年9月29日 Group : Advisory / Atomic model ...
