Summary: Predicted to enable N-acetylglucosaminyl-proteoglycan 4-beta-glucuronosyltransferase activity and acetylglucosaminyltransferase activity. Acts upstream of or within several processes, including axon guidance; embryonic morphogenesis; and proteoglycan biosynthetic process. Predicted to be located in endoplasmic reticulum membrane. Predicted to be active in Golgi apparatus. Is expressed in nervous system and pectoral fin musculature. Used to study hereditary multiple exostoses. Orthologous to human EXT2 (exostosin glycosyltransferase 2). [provided by Alliance of Genome Resources, Oct 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
