Vitamin A homeostasis is critical to normal cellular function. Retinol-binding protein (RBP) is the sole specific carrier in the bloodstream for hydrophobic retinol, the main form in which vitamin A is transported. The integral membrane receptor STRA6 mediates cellular uptake of vitamin A by recognizing RBP-retinol to trigger release and internalization of retinol. We present the structure of zebrafish STRA6 determined to 3.9-angstrom resolution by single-particle cryo-electron microscopy. STRA6 has one intramembrane and nine transmembrane helices in an intricate dimeric assembly. Unexpectedly, calmodulin is bound tightly to STRA6 in a noncanonical arrangement. Residues involved with RBP binding map to an archlike structure that covers a deep lipophilic cleft. This cleft is open to the membrane, suggesting a possible mode for internalization of retinol through direct diffusion into the lipid bilayer. 履歴 登録 2016年5月30日 登録サイト : RCSB / 処理サイト : RCSB改定 1.0 2016年8月24日 Provider : repository / タイプ : Initial release改定 1.1 2016年9月7日 Group : Database references改定 1.2 2017年9月13日 Group : Author supporting evidence / Database references / Derived calculationsカテゴリ : citation / pdbx_audit_support / pdbx_struct_oper_listItem : _citation.journal_id_CSD / _pdbx_audit_support.funding_organization / _pdbx_struct_oper_list.symmetry_operation改定 1.3 2019年12月25日 Group : Author supporting evidence / カテゴリ : pdbx_audit_support / Item : _pdbx_audit_support.funding_organization改定 1.4 2024年4月3日 Group : Data collection / Database references ...
