    Summary
    Enables N-acylmannosamine kinase activity and UDP-N-acetylglucosamine 2-epimerase activity. Involved in N-acetylneuraminate biosynthetic process. Is active in cytosol. Is expressed in several structures, including alimentary system; brain; genitourinary system; hemolymphoid system; and respiratory system. Human ortholog(s) of this gene implicated in GNE myopathy; sialuria; and thrombocytopenia. Orthologous to human GNE (glucosamine (UDP-N-acetyl)-2-epimerase/N-acetylmannosamine kinase).

    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.

      Status: VALIDATED

      Description
      Transcript Variant: This variant (1) contains a different 5' terminal exon compared to transcript variant 1, which results in translation initiation from an in-frame downstream start codon. The resulting protein (isoform 1) has a shorter N-terminus compared to isoform 2. This variant has been called GNE1 in the scientific literature.
