ATP5E

PDB 2jdi EBI.jpg

ATP5E is a gene that encodes a subunit of the ATP synthase enzyme, specifically the epsilon subunit. ATP synthase is a crucial enzyme in the process of cellular respiration, responsible for the synthesis of adenosine triphosphate (ATP), the primary energy carrier in cells.

Function

The ATP5E gene product is a component of the F1 sector of the ATP synthase complex, which is located in the mitochondrial inner membrane. The epsilon subunit plays a role in the regulation of the enzyme's activity, ensuring efficient ATP production during the process of oxidative phosphorylation.

Structure

ATP synthase is a multi-subunit complex composed of two main sectors: the F1 sector and the Fo sector. The F1 sector, where ATP5E is located, is responsible for the catalytic activity of the enzyme. The epsilon subunit, encoded by ATP5E, interacts with other subunits within the F1 sector to stabilize the complex and regulate its function.

Clinical Significance

Mutations in the ATP5E gene can lead to defects in ATP synthase function, which may result in various mitochondrial disorders. These disorders can affect tissues with high energy demands, such as the nervous system, muscles, and heart.

Research

Ongoing research is focused on understanding the precise mechanisms by which ATP5E mutations contribute to mitochondrial dysfunction and exploring potential therapeutic approaches to mitigate these effects.
