Activity summary

ATP5O also known as OLIGOMYCIN SENSITIVITY CONFERRING PROTEIN (OSCP) plays an important role mechanically in the function of mitochondria. It is a component of the F1F0 ATP synthase complex responsible for the generation of ATP from ADP using the proton gradient across the mitochondrial membrane. ATP5O assists in the stabilization of the enzyme structure. The target protein has a molecular mass of approximately 23 kDa. Expression of ATP5O occurs in various tissues especially in muscles and organs with high energy demands such as the heart and liver.

Biological function summary

ATP5O assists in the energy production process by associating with the mitochondrial ATP synthase complex. It interacts closely with other subunits to form the stator stalk which is vital in the maintenance of the enzyme’s structural integrity during ATP synthesis. The proper function of ATP5O ensures effective conversion of the chemiosmotic energy into chemical energy within the mitochondria making metabolism efficient and supporting cellular energy requirements. This makes its role in energy homeostasis invaluable.

Pathways

ATP5O integrates into oxidative phosphorylation a pathway critical for cellular respiration and energy production. It collaborates with other ATP synthase subunits as well as cytochrome c to complete the electron transport chain culminating the release of ATP for cellular function. ATP5O’s activity impacts cellular energy homeostasis and interacts with proteins like ATP5A and ATP5B which are also part of the ATP synthase complex. Its involvement ensures effective energy transfer and metabolic adaptation to cellular demands.

Associated diseases and disorders

ATP5O disruptions have links to mitochondrial disorders and neurodegenerative diseases. Mutations affecting ATP5O function can lead to compromised ATP production resulting in conditions like mitochondrial encephalomyopathy. Additionally dysfunctions in ATP5O may contribute to Alzheimer’s disease due to impaired energy metabolism. The link through disease pathways is often closely associated with proteins in the ATP synthase complex highlighting ATP5O's significance in maintaining mitochondrial and neuronal health.
