Abstract
Most of the functions of LC3/GABARAP in macroautophagy/autophagy are considered to depend on their association with the phagophore membrane through a conjugation to a lipid. Using site-directed mutagenesis, we inhibited the conjugation of LGG-1, the single homolog of GABARAP in C. elegans. Mutants that express only cytosolic forms revealed an essential role for the cleaved form of LGG-1 in autophagy but also in an autophagy-independent embryonic function.
期刊介绍：
Autophagy is a peer-reviewed journal that publishes research on autophagic processes, including the lysosome/vacuole dependent degradation of intracellular material. It aims to be the premier journal in the field and covers various connections between autophagy and human health and disease, such as cancer, neurodegeneration, aging, diabetes, myopathies, and heart disease. Autophagy is interested in all experimental systems, from yeast to human. Suggestions for specialized topics are welcome.
The journal accepts the following types of articles: Original research, Reviews, Technical papers, Brief Reports, Addenda, Letters to the Editor, Commentaries and Views, and Articles on science and art.
Autophagy is abstracted/indexed in Adis International Ltd (Reactions Weekly), EBSCOhost (Biological Abstracts), Elsevier BV (EMBASE and Scopus), PubMed, Biological Abstracts, Science Citation Index Expanded, Web of Science, and MEDLINE.
