Through ... Lysophosphatidylcholine (LPC) is an essential mediator in human lipid metabolism and is associated with a variety of diseases, but the exact identity of LPC receptors remains controversial. Through extensive biochemical and structural analyses, we have identified the orphan receptor GPR119 as the receptor for LPC. The structure of the GPR119-G-protein complex without any added ligands reveals a density map that fits well with LPC, which is further confirmed by mass spectrometry and functional studies. As LPCs are abundant on the cell membrane, their preoccupancy in the receptor may lead to 'constitutive activity' of GPR119. The structure of GPR119 bound to APD668, a clinical drug candidate for type 2 diabetes, reveals an exceedingly similar binding mode to LPC. Together, these data highlight structural evidence for LPC function in regulating glucose-dependent insulin secretion through direct binding and activation of GPR119, and provide structural templates for drug design targeting GPR119. 履歴 登録 2022年6月2日 登録サイト : PDBJ / 処理サイト : PDBJ改定 1.0 2022年8月24日 Provider : repository / タイプ : Initial release改定 1.1 2022年10月5日 Group : Database references / カテゴリ : citationItem : _citation.journal_volume / _citation.page_first / _citation.page_last
