Summary: Enables beta-1,3-galactosyl-O-glycosyl-glycoprotein beta-1,6-N-acetylglucosaminyltransferase activity. Involved in O-glycan processing, core 2 and positive regulation of leukocyte tethering or rolling. Acts upstream of or within kidney morphogenesis and tissue morphogenesis. Predicted to be located in Golgi cisterna; extracellular space; and trans-Golgi network. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; sensory organ; and skeleton. Orthologous to human GCNT1 (glucosaminyl (N-acetyl) transferase 1).

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.
