Acts as the peroxisome receptor for pexophagy. Required for both micropexophagy and macropexophagy, but not for the cytoplasm to vacuole transport (Cvt) or autophagy pathways. Required for functional micropexophagic apparatus (MIPA) and relocation of ATG11 to the peroxisome-sequestering arms of the vacuole. Interacts with ATG11, ATG17, PEX3 and PEX14. Surrounds the peroxisome cluster, but a small amount is also inside the vacuole in methanol-grown cells. Upon induction of micropexophagy, localizes inside the vacuolar lumen. Also localizes near peroxisomes during early stages of micropexophagy. Phosphorylation at Ser-112 is required for micro- and macropexophagy.
