The crystal structure of human WIPI2 bound to the ATG16L1 WIPI2-interacting region, combined with in vitro reconstitution and cellular autophagy assays, shows how the LC3 lipidation machinery is recruited in autophagy initiation.
Proteasomes are protected from autophagic elimination upon carbon starvation by sequestration into cytoplasmic storage granules, which aid cell fitness by providing a cache of proteasomes that can be rapidly remobilized when carbon availability improves.
Parkin ubiquitination of damaged mitochondria recruits the Rab GEF, RABGEF1, to regulate downstream Rab cycles and ATG9A recruitment to growing phagophores that are participating in mitophagy.

The presynaptic scaffolding protein Bassoon is involved in regulating neurotransmitter release by controlling synaptic vesicle pool size and vesicular protein turnover through increased ubiquitination and Parkin-dependent autophagy.
Two GAP proteins bound to mitochondria regulate the enyzme Rab7, and thereby the expansion of the isolation membrane during mitophagy, downstream of PINK1 and Parkin, two proteins that are mutated in familial Parkinson's disease.

Multiplexed mass spectrometry shows how the autophagy gene Atg16l1 regulates macrophage innate immunity against intracellular bacterial pathogens by modulating basal oxidative stress responses.

A pathogen effector mimics starvation-induced autophagy by subverting host endomembrane trafficking to stimulate biogenesis of autophagosomes around pathogen feeding sites, revealing how pathogens interlock distinct host compartments to facilitate infection.

Photodamaged chloroplasts are targeted for vacuolar degradation through microautophagy by the NBR1 autophagy receptor without the participation of the canonical autophagy machinery.
