A genetic interaction is inferred when mutation or over expression of one gene results in suppression of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.

Receptor-mediated clustering of FIP200 bypasses the role of LC3 lipidation in autophagy.

Ohnstad AE, Delgado JM, North BJ, Nasa I, Kettenbach AN, Schultz SW, Shoemaker CJ

Autophagosome formation requires multiple autophagy-related (ATG) factors. However, we find that a subset of autophagy substrates remains robustly targeted to the lysosome in the absence of several core ATGs, including the LC3 lipidation machinery. To address this unexpected result, we performed genome-wide CRISPR screens identifying genes required for NBR1 flux in ATG7KO cells. We find that ATG7-independent autophagy still requires ... [more]
