Protein Structure
UniProt Annotation
Function Glycosyltransferase required for the biosynthesis of heparan-sulfate. The EXT1/EXT2 complex possesses substantially higher glycosyltransferase activity than EXT1 or EXT2 alone. Appears to be a tumor suppressor.
Subcellular Localization Endoplasmic reticulum membrane; Single-pass type II membrane protein. Golgi apparatus membrane; Single-pass type II membrane protein. Note=The EXT1/EXT2 complex is localized in the Golgi apparatus.
Disease Associations
Tissue Specificity Heart, brain, spleen, lung, liver, skeletal muscle, kidney and testis.
