NDUFA11 (NADH:Ubiquinone Oxidoreductase Subunit A11) is a Protein Coding gene. Diseases associated with NDUFA11 include Mitochondrial Complex I Deficiency and Leigh Syndrome. Among its related pathways are Metabolism and Respiratory electron transport, ATP synthesis by chemiosmotic coupling, and heat production by uncoupling proteins. NDUFA11 encodes a subunit of the membrane-bound mitochondrial complex I. Complex I is composed of numerous subunits and functions as the NADH-ubiquinol reductase of the mitochondrial electron transport chain.
