Regulation and significance of acidification of plasma membrane and intracellular membranes / 医学研究生学报

ABSTRACT

Acidic environment of organelles of eukaryotic cells plays an important role in endocytosis, the secretion of lysoso-mal enzymes and other physiological activities.V-ATPase (vacuolar ATPases) and CLC (chloride channel) family are widely distribu-ted and present in virtually all eukaryotic cells in intracellular membranes and in the plasma membrane.They are responsible for the a-cidification of the vesicular interior.In this paper, the distribution, structure, mechanism of action and physiological and pathological significance of V-ATPase and CLC protein are discussed.
