**Background of ATP6V1H (Vacuolar-type Proton ATPase Subunit H)**
ATP6V1H is a critical subunit of the vacuolar-type H+-ATPase (V-ATPase), a multisubunit proton pump responsible for acidifying intracellular compartments, such as lysosomes, endosomes, and secretory vesicles. This acidification is essential for processes like protein degradation, membrane trafficking, and ion homeostasis. V-ATPases consist of two functional domains: the cytosolic V1 complex (ATP hydrolysis) and the membrane-integral V0 complex (proton translocation). The ATP6V1H subunit, encoded by the *ATP6V1H* gene on chromosome 14q24.3 in humans, is part of the V1 domain's peripheral stalk, contributing to structural stability and regulatory interactions.
Studies highlight its role in modulating V-ATPase assembly, localization, and activity. Dysregulation of ATP6V1H is implicated in pathological conditions, including osteoporosis and cancer. For instance, reduced ATP6V1H expression in osteoclasts impairs bone resorption, linking it to skeletal disorders. In cancer, V-ATPase overexpression promotes tumor metastasis by enhancing extracellular acidification, though ATP6V1H-specific mechanisms remain under investigation. Additionally, variants in *ATP6V1H* have been associated with neurodevelopmental disorders and lysosomal storage diseases, underscoring its broad physiological relevance.
Recent research focuses on its structural interactions within the V-ATPase complex and potential as a therapeutic target. Advances in cryo-EM have clarified its conformational role in proton translocation, aiding drug design for diseases tied to pH dysregulation. Despite progress, understanding tissue-specific functions and regulatory networks of ATP6V1H requires further exploration.
