WebJun 4, 2024 · Autophagic cores have two conjugation pathways that attach the product of autophagy-related gene 8 (ATG8) to phosphatidylethanolamine (PE) and ATG5 to ATG12, respectively, which then help with vesicle elongation and enclosure. Rice has six ATG8 genes, which have not been functionally confirmed so far. We identified the rice gene … WebATG8 is an ubiquitin-like protein which can be used as an autophagosome marker in yeast, metazoans, and plants (Fujioka et al., 2008; Kirisako et al., 1999 ), and Arabidopsis has nine genes ( ATG8a–ATG8i) encoding ATG8 isoforms ( Li & Vierstra, 2012 ).

WebThe cellular exclusivity of Atg8–PE conjugation has become well established in the autophagy field. A parallel non-canonical autophagy pathway has since been discovered that utilizes some components of the autophagy machinery to conjugate Atg8-family proteins to single-membranes (CASM) of the endolysosomal system. ...

WebAtg8-positive autophagic bodies accumulate in the vacuoles of pep4 mutant cells under starvation conditions, while little accumulates in the vacuoles of wild type yeast.31,32,40Taken together, these results indicate that, in wild type yeast, intra-autophagosomal Atg8-PE is dramatically degraded in the vacuoles during autophagy. WebATG8–PE becoming imbedded in the membranes of these structures. During deposition of the autophagosome, the ATG8 moiety of the ATG8–PE adduct decorating the outside membrane is possibly released by the ATG4 protease; ATG8–PE decorating the inside membrane enters the vacu-ole along with the autophagic body and is degraded (Kim et …
