    Summary
    Enables alpha-1,3-mannosylglycoprotein 4-beta-N-acetylglucosaminyltransferase activity. Involved in N-glycan processing. Acts upstream of or within protein N-linked glycosylation. Predicted to be located in peroxisome. Predicted to be active in Golgi stack; endoplasmic reticulum; and endoplasmic reticulum-Golgi intermediate compartment. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; nose; and respiratory system. Orthologous to human MGAT4A (alpha-1,3-mannosyl-glycoprotein 4-beta-N-acetylglucosaminyltransferase A). [provided by Alliance of Genome Resources, Dec 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.
