Function

[ATG19_YEAST] 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.^[1] ^[2] ^[3] ^[4] ^[5] ^[6] ^[7] ^[8] ^[9] ^[10] ^[11] ^[12] ^[13] ^[14] ^[15] ^[16]

Publication Abstract from PubMed

Selective autophagy mediates the degradation of various cargoes, including protein aggregates and organelles, thereby contributing to cellular homeostasis. Cargo receptors ensure selectivity by tethering specific cargo to lipidated Atg8 at the isolation membrane. However, little is known about the structural requirements underlying receptor-mediated cargo recognition. Here, we report structural, biochemical, and cell biological analysis of the major selective cargo protein in budding yeast, aminopeptidase I (Ape1), and its complex with the receptor Atg19. The Ape1 propeptide has a trimeric coiled-coil structure, which tethers dodecameric Ape1 bodies together to form large aggregates. Atg19 disassembles the propeptide trimer and forms a 2:1 heterotrimer, which not only blankets the Ape1 aggregates but also regulates their size. These receptor activities may promote elongation of the isolation membrane along the aggregate surface, enabling sequestration of the cargo with high specificity.
