    Summary
    Predicted to enable NADP binding activity. Predicted to be involved in several processes, including cell redox homeostasis; intracellular oxygen homeostasis; and positive regulation of hydrogen peroxide catabolic process. Located in mitochondrial inner membrane. Is expressed in several structures, including alimentary system; brain; musculature; respiratory system; and urinary system. Human ortholog(s) of this gene implicated in familial glucocorticoid deficiency. Orthologous to human NNT (nicotinamide nucleotide transhydrogenase).

    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.
