Lysosomes contain most of the cells supply of labile iron, which makes them sensitive to oxidative stress. To keep lysosomal labile iron at a minimum, a cellular strategy might be to autophagocytose iron-binding proteins that temporarily would chelate iron in a nonredox-active form. Previously we have shown that autophagy of metallothioneins, as well as of non-Fe-saturated ferritin, meets this goal. Here we add another stress-regulated protein to the list, namely HSP70.
