Summaries for NDUFB9 Gene

Entrez Gene Summary for NDUFB9 Gene

  • The protein encoded by this gene is a subunit of the mitochondrial oxidative phosphorylation complex I (nicotinamide adenine dinucleotide: ubiquinone oxidoreductase). Complex I is localized to the inner mitochondrial membrane and functions to dehydrogenate nicotinamide adenine dinucleotide and to shuttle electrons to coenzyme Q. Complex I deficiency is the most common defect found in oxidative phosphorylation disorders and results in a range of conditions, including lethal neonatal disease, hypertrophic cardiomyopathy, liver disease, and adult-onset neurodegenerative disorders. Pseudogenes of this gene are found on chromosomes five, seven and eight. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2015]

GeneCards Summary for NDUFB9 Gene

NDUFB9 (NADH:Ubiquinone Oxidoreductase Subunit B9) is a Protein Coding gene. Diseases associated with NDUFB9 include Mitochondrial Complex I Deficiency and Osgood-Schlatter's Disease. Among its related pathways are Respiratory electron transport, ATP synthesis by chemiosmotic coupling, and heat production by uncoupling proteins. and Metabolism. Gene Ontology (GO) annotations related to this gene include NADH dehydrogenase (ubiquinone) activity.

UniProtKB/Swiss-Prot for NDUFB9 Gene

  • Accessory subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I), that is believed to be not involved in catalysis. Complex I functions in the transfer of electrons from NADH to the respiratory chain. The immediate electron acceptor for the enzyme is believed to be ubiquinone.
