ATP6V1F also known as Vacuolar ATPase subunit F is a component of the V-type ATPase (V-ATPase) complex. This protein has a molecular mass of approximately 13 kDa. ATP6V1F is expressed in various tissues with higher levels observed in kidney heart and skeletal muscle tissues. It plays a mechanical role in proton transport across the vacuolar membrane important for acidifying cellular organelles such as endosomes lysosomes and the Golgi apparatus.

Biological function summary

ATP6V1F plays a critical part in cellular processes such as protein degradation ion homeostasis and membrane trafficking. ATP6V1F is a part of the V-ATPase complex which is essential for maintaining the acidification of intracellular compartments. The proton pump activity of V-ATPase involves ATP hydrolysis where ATP6V1F contributes to its regulation and structural stability. It helps in cellular events that require compartmental pH regulation impacting multiple physiological roles.

Pathways

ATP6V1F interacts with processes like endocytosis and lysosome-mediated degradation. The V-ATPase complex which includes ATP6V1F functions in conjunction with proteins such as Rab5 and clathrin during endocytic pathways and is implicated in mTOR signaling. These interactions underline its involvement in both nutrient sensing and cellular metabolism indicating its significance in cellular nutrient dynamics and homeostasis.

ATP6V1F connects to conditions like neurodegenerative diseases and osteopetrosis. Variations in this protein or its dysfunction can lead to improper acidification of lysosomes contributing to neurological disorders through aggregation of misfolded proteins. Additionally its role in osteoclast-mediated bone resorption relates ATP6V1F to osteopetrosis where excessive bone density occurs due to failed bone resorption. The protein complex V-ATPase and its subunits like ATP6V0D1 and ATP6V1B2 often closely correlate with these conditions illustrating a network of related proteins influencing similar pathways and disease outcomes.
