Summary: Enables beta-1,4-mannosylglycoprotein 4-beta-N-acetylglucosaminyltransferase activity. Acts upstream of or within several processes, including negative regulation of lysosomal protein catabolic process; positive regulation of protein localization to early endosome; and protein N-linked glycosylation. Predicted to be located in Golgi membrane and lysosome. Is expressed in several structures, including alimentary system; metanephros; and nervous system. Orthologous to human MGAT3 (beta-1,4-mannosyl-glycoprotein 4-beta-N-acetylglucosaminyltransferase). [provided by Alliance of Genome Resources, Nov 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.
