Family relationships



Macroautophagy is a bulk degradation process induced by starvation in eukaryotic cells. In yeast, 15 Atg proteins coordinate the formation of autophagosomes. The pre-autophagosomal structure contains at least five Atg proteins: Atg1p, Atg2p, Atg5p, Aut7p/Atg8p and Atg16p. It is found in the vacuole [PMID: 11689437]. The C-terminal glycine of Atg12p is conjugated to a lysine residue of Atg5p via an isopeptide bond. During autophagy, cytoplasmic components are enclosed in autophagosomes and delivered to lysosomes/vacuoles. Auotphagy protein 16 (Atg16) has been shown to be bind to Atg5 and is required for the function of the Atg12p-Atg5p conjugate [PMID: 10406794]. Autophagy protein 5 (Atg5) is directly required for the import of aminopeptidase I via the cytoplasm-to-vacuole targeting pathway [PMID: 10712513].

Autophagy protein 17 (Atg17) forms complex with Atg29 and Atg31, and this complex is critical for both PAS (preautophagosomal structure) formation and autophagy [PMID: 23219485]. This entry also contains Arabidopsis autophagy protein 11 (Atg11), which is an important modulator of the ATG1-ATG13 complex and a multifunctional scaffold required for bulk autophagy and the selective clearance of mitochondria [PMID: 24991832].
