Abstract
Macroautophagy/autophagy can be a selective degradative process via the utilization of various autophagic receptor proteins. Autophagic receptors selectively recognize ubiquitinated cargoes and deliver them to phagophores, the precursors to autophagosomes, for their degradation. For example, SQSTM1/p62 directly binds to ubiquitinated protein aggregates via its UBA domain and sequesters them into inclusion bodies via its PB1 domain. SQSTM1also interacts with phagophores via its LC3-interacting (LIR) motif. However, a regulatory mechanism for autophagic receptors is not yet understood.Entities:
