1 Among a panel of B cell lines, expression of GM1 was negatively correlated with and suppressed by gene expression of CD77 synthase (CD77Syn), whereas no significant positive correlation was found for enzymes actually biosynthesizing GM1. G(M1) Ganglioside alpha 1,4-galactosyltransferase (P blood group) Homo sapiens
2 Among a panel of B cell lines, expression of GM1 was negatively correlated with and suppressed by gene expression of CD77 synthase (CD77Syn), whereas no significant positive correlation was found for enzymes actually biosynthesizing GM1. G(M1) Ganglioside alpha 1,4-galactosyltransferase (P blood group) Homo sapiens
3 Unexpectedly, a GM1-suppressive phenotype was also observed in the expression of catalytically inactive CD77Syn, ruling out catalytic consumption of lactosylceramide (LacCer) as the main cause for such negative regulation. G(M1) Ganglioside alpha 1,4-galactosyltransferase (P blood group) Homo sapiens
