Abstract:
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.

Coat Assembly and GTPases
Coat assembly depends on the local availability of phosphatidylinositol phosphates or PIPs and GTP-binding proteins. Adaptor proteins, which link the coat proteins to the membrane, bind to these PIPs and play a crucial role in controlling...
SNAREs and Membrane Fusion
SNAREs exist in pairs that symmetrically interact and catalyze the fusion of the lipid bilayers in vesicle and target organelle. v-SNARE in the vesicle membrane are single polypeptide chains that bind to a complementary t-SNARE, composed of 2...
