Mining the O-glycoproteome using zinc-finger nuclease-glycoengineered SimpleCell lines

Owing to a lack of tools and a lack of a consensus sequence for O-glycosylation, studies of the O-glycoproteome have been few and far between, despite the biological importance of O-glycosylation. This method to analyze O-glycan attachment sites to proteins using glycoengineered cell lines with simplified, homogenous O-glycoproteomes should facilitate future O-glycoproteomics studies.
