Complementation of a defect in the asparagine-linked glycosylation of a mouse FM3A mutant G258 cell line by spheroplast fusion of a human mega YAC clone 923f5.

Abstract excerpt

Mouse G258 mutant stopped both cell growth and the synthesis of lipid-linked oligosaccharide at the Man(3)GlcNAc(2)-P-P-Dolichol at a restricted temperature with a single gene mutation. To clarify the lesion in the G258 mutant, we isolated human genomic DNA transformants of the G258 mutant, which recovered from both defects by way of cell hybridization with X-ray irradiated HeLa cells. We detected a common 1.3-kb...
