NDUFV3

NDUFV3
PFAM accession number:PF15880
Interpro abstract (IPR026193): NADH dehydrogenase [ubiquinone] flavoprotein 3 (NDUFV3) is a 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 [(PUBMED:1902801), (PUBMED:1778979)].
GO component:mitochondrion (GO:0005739), mitochondrial respiratory chain complex I (GO:0005747)
