General annotation (Comments)

Function

Core subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I) that is believed to belong to the minimal assembly required for 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 By similarity.

Catalytic activity

NADH + ubiquinone + 5 H+(In) = NAD+ + ubiquinol + 4 H+(Out).

Subcellular location

Mitochondrion membrane; Multi-pass membrane protein By similarity.

Sequence similarities

Belongs to the complex I subunit 4 family.
