Function
Glycosyltransferase required for the biosynthesis of heparan sulfate (PubMed:11121397, PubMed:16828468, PubMed:17237233). Initiates heparan sulfate synthesis by transferring GlcNAc to the (GlcA-Gal-Gal-Xyl-)Ser core linker (GlcNAcT-I activity) (PubMed:11121397). In association with rib-1, is also responsible for the alternating addition of beta-1-4-linked glucuronic acid (GlcA) and alpha-1-4-linked N-acetylglucosamine (GlcNAc) units to nascent heparan sulfate chains (GlcNAcT-II and GlcAT-II activities) (PubMed:11121397, PubMed:17237233). Required for normal ventral epidermal enclosure during the early stages of embryonic development (PubMed:17237233). In addition, involved in the elongation of the pharyngeal isthmus during the later stages of embryonic development (PubMed:16828468). Involved in the directed migration of hermaphrodite-specific neurons (PubMed:17237233, PubMed:24052309).
