EMBO J. 2020 Dec 15;39(24):e104948. doi: 10.15252/embj.2020104948. Epub 2020 Nov 23.

In the absence of LC3 lipidation, receptor-mediated clustering of upstream autophagy factors is sufficient to induce local autophagosome formation and enforce cargo specificity.

Here, we set out to build new reporters for studying mammalian autophagy by genetic screening. This approach allowed us to carry out genome-wide CRISPR-mediated knockout screens that recovered virtually all known mammalian autophagy-related (ATG) factors. In addition, we uncovered several uncharacterized proteins, including the endoplasmic reticulum (ER) transmembrane protein 41B (TMEM41B), which we went on to show is required for normal growth of autophagosome precursor membranes around their targets.

Receptor-Bound Targets of Selective Autophagy Use a Scaffold Protein to Activate the Atg1 Kinase.
Kamber RA, Shoemaker CJ, Denic V
Mol Cell. 2015 Aug 6;59(3):372-81. doi: 10.1016/j.molcel.2015.06.009. Epub 2015 Jul 9.

We find that a key function of target-bound autophagy receptors is to activate the autophagy kinase, Atg1, via interactions with the scaffold protein Atg11. Our work thus reveals a mechanism by which target recognition coordinates the earliest steps in autophagosome biogenesis.
