We conclude that brown adipose tissue function in mice does not require the presence of Cox7a1
Title: The brown and brite adipocyte marker Cox7a1 is not required for non-shivering thermogenesis in mice.
We demonstrate a developmental isoform switch of COX6A and COX7A subunits in human and mouse skeletal muscle
Title: Investigating the role of the physiological isoform switch of cytochrome c oxidase subunits in reversible mitochondrial disease.
Data (including data from cells of transgenic mouse embryos) suggest Hif1a (hypoxia inducible factor 1 alpha subunit) up-regulates transcription of heart/muscle isoform Cox7a1 under hypoxia; hypoxic induction of isoform Cox4i2 is HIF1a-independent.
Title: Hypoxia Inducible Factors Modulate Mitochondrial Oxygen Consumption and Transcriptional Regulation of Nuclear-Encoded Electron Transport Chain Genes.
Deletion of the Cox7a1 isoform results in reduced muscle bioenergetics and hindlimb capillarity
Title: Deletion of heart-type cytochrome c oxidase subunit 7a1 impairs skeletal muscle angiogenesis and oxidative phosphorylation.
The authors show that homozygous and heterozygous Cox7a1 knockout mice, although viable, have reduced Cox activity and develop a dilated cardiomyopathy at 6 weeks of age.
Title: Mice deleted for heart-type cytochrome c oxidase subunit 7a1 develop dilated cardiomyopathy.
A significasnt decrease in COX7AH polypeptide was observed in the myocardium of infected mice at 110 dpi, the repression being amplified with chronic disease development (330 dpi).

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.
