    Summary
    Predicted to enable several functions, including amino acid binding activity; glutamine-fructose-6-phosphate transaminase (isomerizing) activity; and identical protein binding activity. Involved in circadian regulation of gene expression. Is expressed in several structures, including alimentary system; brain; genitourinary system; hemolymphoid system; and sensory organ. Used to study congenital myasthenic syndrome 12. Human ortholog(s) of this gene implicated in congenital myasthenic syndrome 12 and obesity. Orthologous to human GFPT1 (glutamine--fructose-6-phosphate transaminase 1). [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.
