Peroxisomal membrane protein PEX13

UniProtKB accession:  Q92968

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Component of the PEX13-PEX14 docking complex, a translocon channel that specifically mediates the import of peroxisomal cargo proteins bound to PEX5 receptor (PubMed:9653144, PubMed:8858165, PubMed:28765278). The PEX13-PEX14 docking complex forms a large import pore which can be opened to a diameter of about 9 nm (By similarity). Mechanistically, PEX5 receptor along with cargo proteins associates with the PEX14 subunit of the PEX13-PEX14 docking complex in the cytosol, leading to the insertion of the receptor into the organelle membrane with the concomitant translocation of the cargo into the peroxisome matrix (PubMed:9653144, PubMed:8858165, PubMed:28765278). Involved in the import of PTS1- and PTS2-type containing proteins (PubMed:9653144, PubMed:8858165).
