Recognition of laminin by integrin receptors is central to the epithelial cell adhesion to basement membrane, but the structural background of this molecular interaction remained elusive. Here, we report the structures of the prototypic laminin receptor α6β1 integrin alone and in complex with three-chain laminin-511 fragment determined via crystallography and cryo-electron microscopy, respectively. The laminin-integrin interface is made up of several binding sites located on all five subunits, with the laminin γ1 chain C-terminal portion providing focal interaction using two carboxylate anchor points to bridge metal-ion dependent adhesion site of integrin β1 subunit and Asn189 of integrin α6 subunit. Laminin α5 chain also contributes to the affinity and specificity by making electrostatic interactions with large surface on the β-propeller domain of α6, part of which comprises an alternatively spliced X1 region. The propeller sheet corresponding to this region shows unusually high mobility, suggesting its unique role in ligand capture. 履歴 登録 2020年6月22日 登録サイト : PDBJ / 処理サイト : PDBJ改定 1.0 2021年6月23日 Provider : repository / タイプ : Initial release改定 1.1 2021年7月7日 Group : Database references / カテゴリ : citation / citation_authorItem : _citation.country / _citation.journal_abbrev ... _citation.country / _citation.journal_abbrev / _citation.journal_id_CSD / _citation.journal_id_ISSN / _citation.pdbx_database_id_DOI / _citation.title / _citation.year 改定 1.2 2021年7月14日 Group : Database references / カテゴリ : citationItem : _citation.journal_volume / _citation.page_first ... _citation.journal_volume / _citation.page_first / _citation.page_last / _citation.pdbx_database_id_PubMed / _citation.title 改定 1.3 2023年11月29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改定 1.4 2024年10月30日 Group : Structure summaryカテゴリ : pdbx_entry_details / pdbx_modification_featureItem : _pdbx_entry_details.has_protein_modification
