New
Tooze et al., London, United Kingdom. In Mol Cell, Jan 2016
GABARAP, unlipidated and lipidated, but not LC3B, GABARAPL1, and GATE-16, specifically promotes ULK kinase activation dependent on the ULK1 LIR motif, elucidating a unique non-hierarchical role for GABARAP in starvation-induced activation of autophagy.
Structural Basis of the Differential Function of the Two C. elegans Atg8 Homologs, LGG-1 and LGG-2, in Autophagy.
New
Zhang et al., Beijing, China. In Mol Cell, Jan 2016
Multicellular organisms have multiple homologs of the yeast ATG8 gene, but the differential roles of these homologs in autophagy during development remain largely unknown.
SLC27A4 regulate ATG4B activity and control reactions to chemotherapeutics-induced autophagy in human lung cancer cells.
New
Guo et al., Bozhou, China. In Tumour Biol, Jan 2016
ATG4B, a cysteine protease required for autophagy, cleaves the C-terminal amino acid of ATG8 family proteins to reveal a C-terminal glycine which is necessary for ATG8 proteins conjugation to phosphatidylethanolamine (PE) and insertion to autophagosome precursor membranes.
The functional and pathologic relevance of autophagy proteases.
Review
López-Otín et al., In J Clin Invest, 2015
This process is coordinated by complex molecular systems, including the ATG8 ubiquitin-like conjugation system and the ATG4 cysteine proteases, which are implicated in the formation, elongation, and fusion of these autophagic vesicles.
Toxic metals and autophagy.
Review
Bhattacharya et al., India. In Chem Res Toxicol, 2014
It is noted that metals/metalloids and nanoparticles prefer ATG8/LC3 as a potent inducer of autophagy in several cell lines or animal cells.
ATG8 localization in apicomplexan parasites: apicoplast and more?
Review
Sahani et al., Tokyo, Japan. In Autophagy, 2014
Recent studies demonstrated that, in the apicomplexan parasites Plasmodium (malaria parasites) and Toxoplasma, ATG8 localizes to the apicoplast, a unique nonphotosynthetic plastid with 4 limiting membranes.
Regulation of autophagy: modulation of the size and number of autophagosomes.
Review
Klionsky et al., Ann Arbor, United States. In Febs Lett, 2014
Specifically, we consider Ume6-ATG8 and Pho23-ATG9 transcriptional regulation in detail, as examples of how nuclear transcription factors and cytosolic machinery cooperate to determine autophagosome size and number, which are the two main mechanistic factors through which autophagy activity is regulated.
Quantitative proteomics identifies NCOA4 as the cargo receptor mediating ferritinophagy.
Impact
Kimmelman et al., Boston, United States. In Nature, 2014
Like known cargo receptors, nuclear receptor coactivator 4 (NCOA4) was highly enriched in autophagosomes, and associated with ATG8 proteins that recruit cargo-receptor complexes into autophagosomes.
In vitro assays of lipidation of Mammalian atg8 homologs.
Review

Ume6 transcription factor is part of a signaling cascade that regulates autophagy.
GeneRIF
Klionsky et al., Ann Arbor, United States. In Proc Natl Acad Sci U S A, 2012
Ume6 is a negative regulator of ATG8 transcription, which acts along with a histone deacetylase complex including Sin3 and Rpd3 to regulate Atg8 levels
