Using a synthesized glycoprotein, beta-galactosidase modified with p-aminophenyl beta-D-galactopyranoside (beta-D-Gal beta-gal), the incorporation of the glycoprotein into bovine brain synaptosomes was studied. The uptake was mediated by a specific receptor to beta-D-galactoside, and was inhibited by GM1 ganglioside. The uptake
