Although P. pastoris is used as an expression system for protein-based vaccines, yeast glycosylation remains largely uncharacterised across immunogens. Here, we characterise N-glycan structures and their site of attachment on Abdala and show how yeast-specific glycosylation decreases binding to the ACE2 receptor and a receptor-binding motif (RBM) targeting antibody compared to the equivalent mammalian-derived RBD. Reduced receptor and antibody binding is attributed to changes in conformational dynamics resulting from N-glycosylation.

In cell studies, thousands of proteins are known to be O-GlcNAcylated, but reference datasets for most tissue types in animals are lacking.

Quadriceps muscles can be used for biopsies, so we envision this dataset to have potential biomedical relevance in detecting aberrant glycoproteins in metabolic diseases and physiological studies.

It is a component of the extracellular matrix, possibly associated with peculiar properties of the invertebrate tissue. The carbohydrate features a chondroitin sulfate core with branches of sulfated α-Fuc linked to position 3 of the β-GlcA. FCSs from different species of sea cucumbers share a similar chondroitin sulfate core but the structure of the sulfated α-Fuc branches varies significantly. The predominant pattern consists of a single unit of sulfated α-Fuc, though some species exhibit branches with multiple α-Fuc units. This comprehensive review focuses on four major aspects of FCS. Firstly, we describe the initial approaches to elucidate the structure of FCS using classical methods of carbohydrate chemistry. Secondly, we highlight the impact of two-dimensional NMR methods in consolidating and revealing further details about the structure of FCS. These studies were conducted by various researchers across different countries and involving multiple species of sea cucumbers. Thirdly, we summarize the biological activities reported for FCS. Our survey identified 104 publications involving FCS from 42 species of sea cucumbers, reporting 10 types of biological activities. Most studies focused on anticoagulant and antithrombotic activities. Finally, we discuss future perspectives for studies related to FCS. These studies aim to clarify the evolutionary advantage for sea cucumbers in developing such a peculiar fucosylated glycosaminoglycan. Additionally, there is a need to identify the enzymes and genes involved in the metabolism of this unique carbohydrate.</p>","PeriodicalId":12766,"journal":{"name":"Glycobiology","volume":" ","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142871861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To date, the exploration of the roles of various glycoforms in specific platelet functions is largely lacking. In this study, a global analysis of intact N-glycopeptides in human platelets was performed to map all the glycopeptides, glycosites and glycans of platelets. The glycopeptides were enriched by the ZIC- hydrophilic interaction chromatography method and then analyzed by Liquid Chromatography-Tandem Mass Spectrometry analysis. A total of 1,425 intact glycopeptides belonging to 190 N-glycoproteins from human platelets were identified. Moreover, 358 glycans modified 328 glycosites from those glycoproteins. Functional analysis revealed that these glycoproteins are involved mainly in processes and pathways related to platelet adhesion. Among the proteins in these adhesion-related annotations, von Willebrand factor, thrombospondin 1and glycoprotein V were found to contain a possible Lewis y structure, and this finding was further verified by immunoprecipitation assays. As a blood group-related antigen, Lewis y was previously reported to exist in human platelets, but its function remains unclear. Since the glycosylation of von Willebrand factor, thrombospondin 1 and glycoprotein V is involved in platelet-collagen adhesion, the importance of Lewis y on platelet function was evaluated by adhesion assays, which demonstrated that the blockade of Lewis y on platelets decreased the adhesion of platelets to collagen I under both static and flow conditions.</p>","PeriodicalId":12766,"journal":{"name":"Glycobiology","volume":"35 2","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143023063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
