Abstract:
Selective autophagy of damaged organelles assures maintenance of cellular homeostasis in eukaryotes. While the mechanisms by which cells selectively remove dysfunctional mitochondria, lysosomes, endoplasmic reticulum and other organelles has been well characterized, little is known about specific autophagy of damaged early endosomes. In our recent study, we uncovered a new role for RABEP1/Rabaptin5, a long-established regulator of early endosome function, in targeting the autophagy machinery to early endosomes damaged by chloroquine or by internalized Salmonella via interaction with RB1CC1/FIP200 and ATG16L1.

Rab Proteins
Rab proteins switch between a cytosolic, GDP-bound inactive state and a membrane-anchored, GTP-bound active state. By themselves, Rabs show slow rates of GDP/GTP exchange and GTP hydrolysis. Thus, Rab proteins are considered...
