Summary: Enables N-acetylglucosaminyl-proteoglycan 4-beta-glucuronosyltransferase activity and acetylglucosaminyltransferase activity. Involved in heparin biosynthetic process; positive regulation of signal transduction; and proteoglycan biosynthetic process. Located in Golgi apparatus and endoplasmic reticulum. Is expressed in organism. Orthologous to human EXT2 (exostosin glycosyltransferase 2). [provided by Alliance of Genome Resources, Apr 2022]

What's a GeneRIF?

Results suggest that all three Drosophila EXT proteins -- tout-velu, brother of tout-velu, and sister of tout-velu -- are required for the biosynthesis of heparan sulfate proteoglycans, and for the gradient formation of morphogens.
