Membrane atg8ylation but not canonical autophagy control retromer-dependent endosomal sorting of cargo, including glucose transporter GLUT1, of general import and of significance for control of tuberculosis.
The core autophagy protein Atg8 plays non-autophagy roles through binding to an integral membrane protein Hfl1, which harbors an unusual Atg8-interacting motif.
Autophagic cargo receptors recruit the E3-like enzyme for Atg8 lipid conjugation to the cargo and thereby promote local formation of Atg8-positive autophagosomal membranes.
Phosphorylation of a core trafficking component, the COPII coat subunit Sec24, regulates cross-talk between the secretory and autophagy machinery during starvation.
Unbiased and targeted genetic approaches reveal a link between sleep and autophagy that could be relevant for sleep function, and for understanding pathological consequences of chronic sleep loss.

Autophagic flux assays in the nematode Caenorhabditis elegans suggest that autophagy decreases during normal aging, whereas long-lived daf-2 and glp-1 mutants maintain autophagic capacity in distinct spatiotemporal-specific manners to extend lifespan.
