Autophagy-related protein 19

UniProtKB accession:  P35193

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Cargo-receptor protein involved in the cytoplasm to vacuole transport (Cvt) and in autophagy. Recognizes cargo proteins, such as APE4, LAP3, LAP4 and AMS1 and delivers them to the pre-autophagosomal structure for eventual engulfment by the autophagosome and targeting to the vacuole. Involved in the organization of the preautophagosomal structure (PAS). ATG19 association with cargo protein is required to localize ATG11 to the PAS. Also involved in endoplasmic reticulum-specific autophagic process, in selective removal of ER-associated degradation (ERAD) substrates, and is essential for the survival of cells subjected to severe ER stress. Also plays a role in regulation of filamentous growth.
