Sperm cells are terminally differentiated cells that are essential for reproduction in sexually reproducing species. Consistent with their highly specialized function, sperm cells harbor a unique proteome containing many proteins not expressed in somatic cells. In contrast, the post-translational landscape of the sperm proteome remains largely unexplored, limiting our understanding of how modifications such as glycosylation impact sperm function and sperm-egg interactions. Here, we used glycopeptide-centric glycoproteomics to comprehensively characterize protein N-glycosylation in sperm from three mammalian species, revealing clear conservation of glycosylation profiles. We find that glycosylation patterns in sperm proteins are distinct from those in plasma, with as clear distinctive features less sialyation and more paucimannosylation in sperm. Moreover, based on their subcellular location, sperm protein glycosylation varies, with paucimannose species enriched in the acrosomal vesicle, oligomannose species in the sperm head membrane, and complex glycan species in the acrosomal membrane.

Molecular & Cellular Proteomics

The mission of MCP is to foster the development and applications of proteomics in both basic and translational research. MCP will publish manuscripts that report significant new biological or clinical discoveries underpinned by proteomic observations across all kingdoms of life. Manuscripts must define the biological roles played by the proteins investigated or their mechanisms of action.

The journal also emphasizes articles that describe innovative new computational methods and technological advancements that will enable future discoveries. Manuscripts describing such approaches do not have to include a solution to a biological problem, but must demonstrate that the technology works as described, is reproducible and is appropriate to uncover yet unknown protein/proteome function or properties using relevant model systems or publicly available data.
Scope:
-Fundamental studies in biology, including integrative "omics" studies, that provide mechanistic insights
-Novel experimental and computational technologies
-Proteogenomic data integration and analysis that enable greater understanding of physiology and disease processes
-Pathway and network analyses of signaling that focus on the roles of post-translational modifications
-Studies of proteome dynamics and quality controls, and their roles in disease
-Studies of evolutionary processes effecting proteome dynamics, quality and regulation
-Chemical proteomics, including mechanisms of drug action
-Proteomics of the immune system and antigen presentation/recognition
-Microbiome proteomics, host-microbe and host-pathogen interactions, and their roles in health and disease
-Clinical and translational studies of human diseases
-Metabolomics to understand functional connections between genes, proteins and phenotypes
