Summary: Enables O-fucosylpeptide 3-beta-N-acetylglucosaminyltransferase activity. Involved in lymphocyte differentiation; negative regulation of Notch signaling pathway involved in somitogenesis; and somitogenesis. Acts upstream of or within several processes, including compartment pattern specification; positive regulation of Notch signaling pathway; and regulation of somitogenesis. Predicted to be located in Golgi membrane. Is expressed in several structures, including alimentary system; embryo ectoderm; genitourinary system; inner ear; and paraxial mesenchyme. Human ortholog(s) of this gene implicated in spondylocostal dysostosis. Orthologous to human LFNG (LFNG O-fucosylpeptide 3-beta-N-acetylglucosaminyltransferase).

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.
