Summary: Enables acetylglucosaminyltransferase activity. Involved in several processes, including positive regulation of epithelial to mesenchymal transition; positive regulation of intracellular signal transduction; and transforming growth factor beta receptor signaling pathway. Predicted to be located in Golgi apparatus. Is expressed in several structures, including alimentary system; extraembryonic component; nervous system; nose; and trunk mesenchyme. Human ortholog(s) of this gene implicated in cataract and cataract 13 with adult i phenotype. Orthologous to human GCNT2 (glucosaminyl (N-acetyl) transferase 2 (I blood group)).

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.
