Description
UDP-galactosyltransferase (b4GalT1) is a trans-Golgi membrane bound protein that participates in protein processing in the Golgi apparatus. UDP-galactosyltransferase catalyzes the transfer of galactose from UDP-galactose to N-acetyl-D-glucosamine. The exclusive location of UDP-galactosyltransferase in the Golgi apparatus in the vast majority of tissues and cells, makes it a convenient biochemical marker for Golgi membranes
