The LIR motif – crucial for selective autophagy

(Macro)autophagy is a fundamental degradation process for macromolecules and organelles of vital importance for cell and tissue homeostasis. Autophagy research has gained a strong momentum in recent years because of its relevance to cancer, neurodegenerative diseases, muscular dystrophy, lipid storage disorders, development, ageing and innate immunity. Autophagy has traditionally been thought of as a bulk degradation process that is mobilized upon nutritional starvation to replenish the cell with building blocks and keep up with the energy demand. This view has recently changed dramatically following an array of papers describing various forms of selective autophagy. A main driving force has been the discovery…
