NDUFA5
Function
Accessory subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I), that is believed not to be 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.
Sequence Similarities
Belongs to the complex I NDUFA5 subunit family.
Tissue Specificity
Expressed in all tissues examined with highest levels in heart, skeletal muscle and brain.
Cellular localization
- Mitochondrion inner membrane
- Peripheral membrane protein
- Matrix side
