Protocol to measure endogenous GlcNAc-1-phosphotransferase activity in SK-MEL-30 cells

Summary: GlcNAc-1-phosphotransferase (GNPT) is the key enzyme for tagging lysosomal hydrolases with the mannose 6-phosphate moiety for delivery to the lysosome. Here, we present the assay for measuring endogenous GNPT activity in SK-MEL-30 cells. We provide details for preparing the [3H]UDP-GlcNAc d...
