{"doi":"10.1042/bst20220713","title":"Mammalian cargo receptors for endoplasmic reticulum-to-Golgi transport: mechanisms and interactions","abstract":"<jats:p>Proteins that are destined to enter the secretory pathway are synthesized on the rough endoplasmic reticulum (ER) and then translocated into the ER lumen, where they undergo posttranslational modifications, folding, and assembly. After passing a quality control system, the cargo proteins are packaged into coat protein complex II (COPII) vesicles to exit the ER. In metazoans, most COPII subunits have multiple paralogs, enabling COPII vesicles the flexibility to transport a diverse range of cargo. The cytoplasmic domains of transmembrane proteins can interact with SEC24 subunits of COPII to enter the ER exit sites. Some transmembrane proteins may also act as cargo receptors that bind soluble secretory proteins within the ER lumen, enabling them to enter COPII vesicles. The cytoplasmic domains of cargo receptors also contain coat protein complex I binding motifs that allow for their cycling back to the ER after unloading their cargo in the ER-Golgi intermediate compartment and cis-Golgi. Once unloaded, the soluble cargo proteins continue maturation through the Golgi before reaching their final destinations. This review provides an overview of receptor-mediated transport of secretory proteins from the ER to the Golgi, with a focus on the current understanding of two mammalian cargo receptors: the LMAN1–MCFD2 complex and SURF4, and their roles in human health and disease.</jats:p>","journal":"Biochemical Society Transactions","year":2023,"id":16563,"datarank":0.747394551179198,"base_score":3.1354942159291497,"endowment":3.1354942159291497,"self_citation_contribution":0.47032413238937254,"citation_network_contribution":0.27707041878982547,"self_endowment_contribution":0.47032413238937254,"citer_contribution":0.27707041878982547,"corpus_percentile":null,"corpus_rank":null,"citation_count":22,"citer_count":21,"citers_with_citation_signal":14,"citers_with_endowment":14,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":null,"fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":121796,"name":"Vishal Srivastava","orcid":null,"position":1,"is_corresponding":false},{"id":108570,"name":"Bin Zhang","orcid":"0009-0006-0660-0375","position":2,"is_corresponding":false},{"id":32274,"name":"Yuan Zhang","orcid":"0000-0001-5147-7069","position":0,"is_corresponding":false}],"reference_count":0,"raw_metadata":{"has_enrichment":true,"base_score":3.1354942159291497,"endowment":3.1354942159291497,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"37334845","pmcid":null,"openalex_id":"https://openalex.org/W4381250217","authors":[],"funders":[{"funder_name":"National Institutes of Health","grant_id":"5R01HL094505-13","title":"ER-to-Golgi transport of coagulation factors V and VIII"},{"funder_name":"NHLBI NIH HHS","grant_id":"R01 HL094505","title":null}],"total_grants":2,"fwci":4.3176,"citation_percentile":0.94685153,"influential_citations":0,"citation_trend":[{"year":2023,"count":1},{"year":2024,"count":4},{"year":2025,"count":14},{"year":2026,"count":3}],"oa_status":"hybrid","license":"cc-by","oa_locations":[{"url":"https://portlandpress.com/biochemsoctrans/article-pdf/doi/10.1042/BST20220713/947281/bst-2022-0713c.pdf","host_type":"journal"},{"url":"https://portlandpress.com/biochemsoctrans/article-pdf/doi/10.1042/BST20220713/947281/bst-2022-0713c.pdf","host_type":"HYBRID"},{"url":"https://portlandpress.com/biochemsoctrans/article-pdf/doi/10.1042/BST20220713/947281/bst-2022-0713c.pdf","host_type":"publisher"},{"url":"https://portlandpress.com/biochemsoctrans/article-pdf/51/3/971/947655/bst-2022-0713c.pdf","host_type":"publisher"},{"url":"https://doi.org/10.1042/bst20220713","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/37334845","host_type":"repository"},{"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/10317151","host_type":"repository"},{"url":"https://pmc.ncbi.nlm.nih.gov/articles/PMC10317151/pdf/BST-51-971.pdf","host_type":"repository"},{"url":"http://dx.doi.org/10.1042/BST20220713","host_type":""}],"fields_of_study":["Cellular transport and secretion","Pancreatic function and diabetes","Genetics and Neurodevelopmental Disorders","Medicine","Biology","Animals","Humans","Endoplasmic Reticulum","Golgi Apparatus","Carrier Proteins","Membrane Proteins","Protein Transport","COP-Coated Vesicles","Mammals"],"mesh_terms":["Animals","Carrier Proteins","Endoplasmic Reticulum","Golgi Apparatus","Humans","Mammals","Membrane Proteins","Protein Transport","COP-Coated Vesicles"],"keywords":["Endoplasmic reticulum","Golgi apparatus","Cell biology","Receptor","Chemistry","Biology","Biochemistry","Mammals","Protein Transport","Animals","Humans","Membrane Proteins","COP-Coated Vesicles","Carrier Proteins","Review Articles","LMAN1–MCFD2","SURF4","glycoproteins","trafficking"],"sdg_mappings":[{"sdg_number":3,"sdg_label":"3.
