The selectivity and individual roles of the N-linked oligosaccharide chains of Sendai virus fusion protein (F protein) in the interaction with endoplasmic reticulum molecular chaperones were investigated by analyses of transient expression of single N-glycosylation mutants and sequential immunoprecipitation. We demonstrated differential interactions depending on the location of the N-linked oligosaccharide chain, and showed that these interactions were correlated with the folding and transport of F proteins. Moreover, mutant F proteins that lacked the specific N-linked oligosaccharide chains required for disulfide bond formation showed increased association with ERp57.
