MT-ATP8
Location of the MT-ATP8 gene in the human mitochondrial genome. MT-ATP8 is one of the two ATP synthase mitochondrial genes (red boxes).
The 46-nucleotide overlap in the reading frames of the human mitochondrial genes MT-ATP8 and MT-ATP6. For each nucleotide triplet (square brackets), the corresponding amino acid is given (one-letter code), either in the +1 frame for MT-ATP8 (in red) or in the +3 frame for MT-ATP6 (in blue).
The protein
ATP synthase protein 8 is a subunit of mitochondrial ATP synthase.
This protein subunit appears to be an integral component of the stator stalk in yeast mitochondrial F-ATPases.[2] The stator stalk is anchored in the membrane, and acts to prevent futile rotation of the ATPase subunits relative to the rotor during coupled ATP synthesis/hydrolysis. This subunit may have an analogous function in Metazoa.
Subunit 8 differs in sequence between Metazoa, plants and Fungi.
The gene
The ATP synthase protein 8 of human and other mammals is encoded in the mitochondrial genome by the MT-ATP8 gene. When the complete human mitochondrial genome was first published, the MT-ATP8 gene was described as the unidentified reading frame URF A6L.[3]
An unusual feature of the MT-ATP8 gene is its 46-nucleotide overlap with the MT-ATP6 gene. With respect to the reading frame (+1) of MT-ATP8, the MT-ATP6 gene starts on the +3 reading frame.
