function: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.,similarity:Belongs to the complex I NDUFA5 subunit family.,subunit:Complex I is composed of 45 different subunits.,tissue specificity:Expressed in all tissues examined with highest levels in heart, skeletal muscle and brain.,
Mitochondrion inner membrane ; Peripheral membrane protein ; Matrix side .
Expressed in all tissues examined with highest levels in heart, skeletal muscle and brain.
