UniProt data
UniProt name: NDUB4_HUMAN (O95168)
Gene name: NDUFB4
Organism: Homo sapiens (Human).
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 location: Mitochondrion inner membrane; Single-pass membrane protein; Matrix side.
Transmembrane domains:
- 88-105, 18 AA, Helical. {ECO:0000255}.
Sequence: 129 AA
