The beta-1,4-galactosyltransferase (beta-1,4-GalT) V whose human and mouse genes were cloned by us has been suggested to be involved in the biosynthesis of N-glycans and O-glycans, and lactosylceramide. To determine its biological function, beta-1,4-GalT V (B4galt5) mutant mice obtained by a gene trap method were analyzed. Analysis of pre- and(More)
Human β-1,4-galactosyltransferase (β-1,4-GalT) V was shown to be involved in the biosynthesis of N-glycans, O-glycans and lactosylceramide (Lac-Cer) by in vitro studies. To determine its substrate specificity, enzymatic activity and its products were analyzed using mouse embryonic fibroblast (MEF) cells from β-1,4-GalT V (B4galt5)-mutant mice. Analysis of(More)
