Autophagy-related protein 19

Gene

Status

Functioni

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. Plays also a role in regulation of filamentous growth.16 Publications

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
