    Summary
    Predicted to enable mannosyl-oligosaccharide 1,2-alpha-mannosidase activity. Predicted to be involved in mannose trimming involved in glycoprotein ERAD pathway and protein targeting to ER. Located in Golgi membrane. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; hindlimb mesenchyme; and sensory organ. Orthologous to human MAN1A1 (mannosidase alpha class 1A member 1). [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.
