Opsin3-knockout (Opn3-KO) mice are prone to diet-induced obesity and insulin resistance. Opn3-KO brown adipocytes cultured in darkness have decreased glucose uptake and lower nutrient-induced mitochondrial respiration than wild-type (WT) cells. Direct exposure of brown adipose tissue (BAT) to light in living mice significantly enhances thermogenic capacity of BAT, and this effect is diminished in Opn3-KO animals.

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.
