Webb11 maj 2024 · Lysosomes digest extracellular material from the endocytic pathway and intracellular material from the autophagic pathway. This process is performed by the resident hydrolytic enzymes activated by the highly acidic pH within the lysosomal lumen. Lysosome pH gradients are mainly maintained by the vacuolar (H+) ATPase (or V … WebbLysosomes have a low pH (4.5 to 5.5), not high. This low pH is required for their enzymes to function. The membrane that encloses a lysosome is a phospholipid–protein bilayer …
WebbGiven the importance of luminal pH for their function, lysosomes have a specific membrane transporter, called the V-ATPase, that pumps protons from the cytosol to the lysosomal lumen to keep their interior acidic. TMEM175 balances the activity of V-ATPase by mediating the lysosomal proton leak and maintaining lysosome pH homeostasis. Webb14 maj 2024 · Long known as digestive organelles, lysosomes have now emerged as multifaceted centers responsible for degradation, nutrient sensing, and immunity. Growing evidence also implicates role of lysosome-related mechanisms in pathologic process. In this review, we discuss physiological function of lysosomes and, more importantly, how …
