UniProt data
UniProt name: NDUB1_HUMAN (O75438)
Gene name: NDUFB1
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:
- 11-27, 17 AA, Helical. {ECO:0000255}.
Sequence: 58 AA
