Protein attributes

Sequence length	175 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

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.
Subunit structure	Mammalian complex I is composed of 45 different subunits. This is a component of the iron-sulfur (IP) fragment of the enzyme By similarity.
Subcellular location	Mitochondrion inner membrane; Peripheral membrane protein; Matrix side By similarity.
Sequence similarities	Belongs to the complex I NDUFS4 subunit family.
Sequence caution	The sequence AAD30474.1 differs from that shown. Reason: Erroneous initiation.
