This protein with a molecular mass of approximately 9 kDa helps assemble the V-ATPase complex which is important for acidifying vacuoles. VMA21 is expressed in many tissues with higher levels observed in metabolically active tissues due to their need for efficient ion transport and pH regulation.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nVMA21 is an important factor in assembling the V-ATPase complex located in the membranes of vacuoles. The V-ATPase is a proton pump that regulates the pH within organelles by transporting hydrogen ions. VMA21 stabilizes the subunits of V-ATPase allowing its correct function in processes like protein degradation and recycling. This regulation is essential for maintaining a balance in the acidic environment necessary for various cellular processes.\u003cbr\u003e\nPathways\u003cbr\u003e\nVMA21 interacts with the V-ATPase complex impacting the lysosomal acidification and nutrient sensing pathways. It connects with the mTORC1 signaling cascade by affecting lysosomal pH which in turn influences cell growth and metabolism. The protein also has indirect ties with SNARE proteins involved in vesicular transport exemplifying its role in broader biological activities.\u003cbr\u003e\nVMA21 associates with X-linked Myopathy with Excessive Autophagy (XMEA). Mutations in VMA21 impair the V-ATPase activity leading to deficient lysosomal acidification and autophagy dysregulation. This impairment results in muscle disease characterized by increased autophagic vacuoles. VMA21 also affects other proteins involved in autophagy such as LC3 indicating its extensive role in muscle pathology and metabolic disorders.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46848640549033,"sku":"ab242115","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/abcam-ab242115","provider":"Iright","version":"1.0","type":"link"}
