The evolutionarily conserved interaction between LC3 and p62 selectively mediates autophagy-dependent degradation of mutant huntingtin.

Abstract excerpt

Mammalian p62/sequestosome-1 protein binds to both LC3, the mammalian homologue of yeast Atg8, and polyubiquitinated cargo proteins destined to undergo autophagy-mediated degradation. We previously identified a cargo receptor-binding domain in Atg8 that is essential for its interaction with the cargo receptor Atg19 in selective autophagic processes in yeast. We, thus, sought to determine whether this interaction...
