    Summary
    Predicted to enable NADP binding activity. Involved in several processes, including cell redox homeostasis; intracellular oxygen homeostasis; and positive regulation of hydrogen peroxide catabolic process. Predicted to be located in mitochondrion. Biomarker of obesity. Human ortholog(s) of this gene implicated in familial glucocorticoid deficiency. Orthologous to human NNT (nicotinamide nucleotide transhydrogenase). [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.
