摘要: Protein O-mannosylation is a special type of glycosylation that plays prominent roles in metazoans, affecting development and physiology the nervous system muscles. A major biological effect involves regulation α-dystroglycan, membrane glycoprotein mediating cell–extracellular matrix interactions. Genetic defects result loss ligand-binding activity α-dystroglycan cause congenital muscular dystrophies termed dystroglycanopathies. Recent progress mass spectrometry vitro analyses has shed new light on mechanism glycosylation; however, this underlain by complex genetic molecular elements remain poorly understood. evolutionarily conserved yet pathway simplified more amenable to invertebrate organisms, indicating genetically tractable vivo models could facilitate research area. This unit describes recent methodological strategies for studying protein using approaches. Curr. Protoc. Sci. 75:12.12.1-12.12.29. © 2014 John Wiley & Sons, Inc.
