Towards a thorough understanding of mammalian glycosylphosphatidylinositol-anchored protein biosynthesis.

Glycosylphosphatidylinositols (GPIs) are glycolipids found ubiquitously in eukaryotes. They consist of a glycan and an inositol phospholipid, and act as membrane anchors of many cell-surface proteins by covalently linking to their C-termini. GPIs also exist as unlinked, free glycolipids on the cell surface. In human cells, at least 160 proteins with various functions are GPI-anchored proteins. Because the attachment of GPI is required for the cell-surface expression of GPI-anchored proteins, a thorough knowledge of the molecular basis of mammalian GPI-anchored protein biosynthesis is important for understanding the basic biochemistry and biology of GPI-anchored proteins and their medical significance. In this paper, I review our previous knowledge of the biosynthesis of mammalian GPI-anchored proteins and then examine new findings made since 2020. © The Author(s) 2024.
