Cargo-receptor protein involved in the cytoplasm to vacuole transport (Cvt) and in autophagy. Recognizes cargo proteins, such as AMS1 and delivers them to the pre-autophagosomal structure for eventual engulfment by the autophagosome and targeting to the vacuole. Interacts with AMS1, ATG8 and ATG11. Membrane-associated protein found in pre-autophagosomal structure and other perivacuolar punctate structures.
