Protein glycosylation is one of the most abundant and widespread post-translational modifications (PTMs). It is involved in many biological processes including host-pathogen interactions and protein quality control. The study of glycosylation in protozoan parasites is especially valuable. Not only it addresses key aspects of pathogen biology but can also provide insights in the evolution of glycosylation pathways, as these are early divergent eukaryotes. In this talk I will focus on Toxoplasma gondii, an opportunistic pathogen of humans, and the function of glycosylation in both the quality control and kinetics of protein folding and stabilisation. I will highlight what we know and what we don’t know about the glycosylation pathways that can affect protein homeostasis in the parasite and provide the example of TgSPY, a paralog of host O-GlcNAc transferase. TgSPY modifies Toxoplasma nucleocytoplasmic proteins with O-fucose and this modification has implications for protein expression and virulence. Biochemical and functional studies on this glycosyltransferase can advance our understanding of glycosylation in eukaryotic cells while also reporting back on fundamental parasite processes.
