UniProt ID: Q6PBN0 |
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. {ECO:0000256|ARBA:ARBA00003195}. SUBUNIT: Complex I is composed of 45 different subunits. {ECO:0000256|ARBA:ARBA00011533}. SUBCELLULAR LOCATION: Mitochondrion inner membrane {ECO:0000256|ARBA:ARBA00004443}; Peripheral membrane protein {ECO:0000256|ARBA:ARBA00004443}; Matrix side {ECO:0000256|ARBA:ARBA00004443}. SIMILARITY: Belongs to the complex I NDUFB2 subunit family. {ECO:0000256|ARBA:ARBA00005923}. |
