Receptor required for the peroxisomal import of proteins containing an N-terminal PTS2-type peroxisomal targeting signal (PubMed:11931631, PubMed:22057399, PubMed:25538232, PubMed:9090381, PubMed:40739340). Specifically binds to cargo proteins containing a PTS2 peroxisomal targeting signal in the cytosol (PubMed:11931631, PubMed:22057399, PubMed:25538232). Cargo protein-binding triggers interaction with PEX5 and formation of a ternary complex composed of PEX5 and PEX7 along with PTS2-containing cargo proteins, which is translocated into peroxisomes by passing through the PEX13-PEX14 docking complex (PubMed:11546814, PubMed:25538232). {ECO:0000269|PubMed:11546814, ECO:0000269|PubMed:11931631, ECO:0000269|PubMed:22057399, ECO:0000269|PubMed:25538232, ECO:0000269|PubMed:40739340, ECO:0000269|PubMed:9090381}. This is the function of Ensembl gene identifier ENSG00000112357 (PEX7, peroxisomal biogenesis factor 7).
