ATP5J2
ATP5J2: A Mitochondrial Protein with a Vital Role in Energy Metabolism
Description
ATP5J2 is a mitochondrial protein encoded by the ATP5J2 gene. It is an essential component of the mitochondrial ATP synthase complex, which plays a crucial role in cellular energy production. ATP synthase is responsible for generating ATP (adenosine triphosphate), the primary energy currency of cells.
ATP5J2 is a transmembrane protein located in the inner mitochondrial membrane. It forms a subunit of the c-ring within the ATP synthase complex, which is responsible for the rotation of the γ subunit and the subsequent synthesis of ATP.
Associated Diseases
Mutations in the ATP5J2 gene have been linked to several human diseases, including:
- Mitochondrial Encephalomyopathy with Lactic Acidosis and Stroke-Like Episodes (MELAS): MELAS is a rare genetic disorder caused by mutations in mitochondrial genes, including ATP5J2. It is characterized by episodes of stroke-like symptoms, seizures, muscle weakness, and lactic acidosis.
- Leber's Hereditary Optic Neuropathy (LHON): LHON is an inherited condition affecting vision. Mutations in ATP5J2 and other mitochondrial genes can lead to LHON, causing sudden loss of central vision in young adulthood.
- Mitochondrial Myopathy: Mutations in ATP5J2 have also been linked to mitochondrial myopathy, a condition characterized by muscle weakness and fatigue.
Did you Know ?
- Approximately 1 in 5,000 individuals weltweit have a mutation in the ATP5J2 gene.
