    Summary
    Enables galactosyltransferase activity. Predicted to be involved in protein O-linked glycosylation. Predicted to act upstream of or within globoside biosynthetic process and plasma membrane organization. Predicted to be located in membrane. Orthologous to human A4GALT (alpha 1,4-galactosyltransferase (P1PK blood group)). [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.
