Mutant HTT (huntingtin) impairs mitophagy in a cellular model of Huntington disease.

abstract：:Macroautophagy is induced under various stresses to remove cytotoxic materials, including misfolded proteins and their aggregates. These protein cargoes are collected by specific autophagic receptors such as SQSTM1/p62 (sequestosome 1) and delivered to phagophores for lysosomal degradation. To date, little is known ab...
