Comments [?]

case <OC:Mammalia>
Function ATP-dependent serine protease that mediates the selective degradation of misfolded and unassembled polypeptides in the peroxisomal matrix. Necessary for type 2 peroxisome targeting signal (PTS2)-containing protein processing and facilitates peroxisome matrix protein import. May indirectly regulate peroxisomal fatty acid beta-oxidation through degradation of the self-processed forms of TYSND1.
Subunit Interacts with PEX5. Interacts with TYSND1.

end case
Subcellular location Peroxisome matrix.
Similarity Belongs to the peptidase S16 family.
