Dolichyl phosphate supplementation increases N-linked protein glycosylation in rat parotid acinar cells without increasing glycoprotein secretion.
N-linked protein glycosylation was increased three- to five-fold, in dispersed rat parotid acinar cells in vitro, by supplementation with exogenous dolichylphosphate. Despite this increase, glycoprotein secretion from both control and dolichylphosphate-supplemented cells was comparable.
