Peroxisomal protein PEX21

UniProtKB accession:  P50091

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Receptor that mediates peroxisomal import of proteins containing a C-terminal PTS2-type peroxisomal targeting signal via its interaction with PEX7 (PubMed:12167700, PubMed:9864360, PubMed:23812376). Interaction with PEX7 only takes place when PEX7 is associated with cargo proteins containing a PTS2 peroxisomal targeting signal (By similarity). PEX7 along with PTS2-containing cargo proteins are then translocated through the PEX13-PEX14 docking complex together with PEX21 (PubMed:23812376). Acts as an activator of the seryl-tRNA synthetase SES1 by increasing its binding to tRNA (PubMed:12204379, PubMed:17451428).
