Gene Symbol

NDUFB3

Protein Name

NADH dehydrogenase (ubiquinone) 1 beta subcomplex, 3, 12kDa

Synonyms

B12; CI-B12;

Species

Homo sapiens

Ensembl Protein

ENSP00000237889

InnateDB Gene

IDBG-78368 (NDUFB3)

Protein Structure

UniProt Annotation

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.

Subcellular Localization

Mitochondrion inner membrane; Single-pass membrane protein; Matrix side.
