Name  Autophagy-related protein 9 Short Name  Autophagy-rel_prot_9
Type  Family Description  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 []. 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 []. Autophagy protein 5 (Atg5) is directly required for the import of aminopeptidase I via the cytoplasm-to-vacuole targeting pathway [].Apg9 plays a direct role in the formation of the cytoplasm to vacuole targeting and autophagic vesicles, possibly serving as a marker for a specialised compartment essential for these vesicle-mediated alternative targeting pathways [].
