title: O-glycosylation in Saccharomyces cerevisiae is initiated at the endoplasmic reticulum.
abstract: The first mannose of O-linked oligomannose chains in S. cerevisiae is transferred to Ser/Thr residues via dolichylphosphate mannose. Only this reaction (and not the subsequent reactions requiring GDP-Man) proceeds at the endoplasmic reticulum.
