Overview
Mermaid diagram (expand to render)
NDUFA1 (NADH:Ubiquinone Oxidoreductase Subunit A1) is a mitochondrial gene encoding a core subunit of Complex I (NADH dehydrogenase) in the electron transport chain. This gene is essential for mitochondrial respiratory function and has been implicated in neurodegenerative diseases including Parkinson's disease, Alzheimer's disease, and Leigh syndrome.
Function
NDUFA1 encodes a core subunit of NADH dehydrogenase (Complex I), the largest enzyme of the mitochondrial respiratory chain. Complex I catalyzes the transfer of electrons from NADH to ubiquinone, pumping protons across the inner mitochondrial membrane to create the electrochemical gradient necessary for ATP synthesis. NDUFA1 is one of the 14 core subunits essential for Complex I assembly and catalytic activity. The protein contains predicted transmembrane helices and is integrated into the membrane arm of Complex I.
Disease Associations
Mitochondrial Complex I Deficiency, Leigh Syndrome
Brain Expression
NDUFA1 is expressed ubiquitously in all human tissues, with high expression in energy-demanding tissues including brain (especially cerebellar [neurons](/entities/neurons), hippocampal pyramidal cells), heart, skeletal muscle, and kidney. Expression is elevated during neural development and in regions with high mitochondrial density.
