Atg8-pe
WebThe inability to deconjugate Atg8–PE results in its mislocalization and in defects in the Cvt and autophagy pathways. The expression of an Atg8 variant, Atg8ΔR, which lacks the C-terminal arginine, in an atg4Δ atg8Δ mutant strain allows the initial step of Atg4-mediated cleavage of Atg8 to be bypassed while still obtaining conjugation of Atg8. . Thus, in this … 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 …

WebJul 13, 2007 · As reported previously (Ichimura et al., 2004), when purified Atg8 G116 (hereafter, referred to as Atg8), Atg7, and Atg3 were incubated with liposomes … WebThe processed ATG8 proteins are then conjugated to PE through an amide bond between the glycine residue of ATG8 and the amino group of PE (Ichimura et al., 2000). This lipidation of ATG8 leads to its localization to the preautophagosomal structure where it is thought to play a role in autophagosome formation ( Kirisako et al., 1999 ).

Before nitrogen starvation, wild-type cells displayed a basal level of Atg8, and even after a short 15-min period of nitrogen starvation, an increase in Atg8–PE could be detected (Fig. 3B).
WebJun 1, 2012 · It is shown that the deconjugation of Atg8−PE by the cysteine protease Atg4 plays dual roles in the formation of autophagosomes, a central step in the well-conserved intracellular degradation pathway of macroautophagy. Modification of target molecules by ubiquitin or ubiquitin-like (Ubl) proteins is generally reversible. Little is known, however, … WebWe show that RFP-Atg8-PE is recruited to autophagosomes in conidiation-related cell types. We confirm that the loss of ATG8 causes pleiotropic defects during asexual …
WebAtg8-PE degrades gradually with extension of amino acid starvation, and bafilomycin A1 can block the decrease through the inhibition of autophagosome fusion with lysosome. Interestingly, high pH is more effective than amino acid starvation in Bombyx mori Bme cells to induce the conversion of BmAtg8 to BmAgt8-PE.
