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. May donate electrons to ubiquinone.

Catalytic activity

NADH + ubiquinone = NAD+ + ubiquinol.

NADH + acceptor = NAD+ + reduced acceptor.

Cofactor

Binds 2 4Fe-4S clusters per subunit By similarity.

Subunit structure

Mammalian complex I is composed of 45 different subunits. Ref.5

Subcellular location

Mitochondrion Probable.

Involvement in disease

Leigh syndrome (LS) [MIM:256000]: An early-onset progressive neurodegenerative disorder characterized by the presence of focal, bilateral lesions in one or more areas of the central nervous system including the brainstem, thalamus, basal ganglia, cerebellum and spinal cord. Clinical features depend on which areas of the central nervous system are involved and include subacute onset of psychomotor retardation, hypotonia, ataxia, weakness, vision loss, eye movement abnormalities, seizures, and dysphagia.
Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.7

Sequence similarities

Belongs to the complex I 23 kDa subunit family.

Contains 2 4Fe-4S ferredoxin-type domains.
