NCBI Protein Information
peroxin4
NCBI Summary
mutant displays sucrose-dependent seedling development and reduced lateral root production. PEX4 interacts with PEX22 in a yeast two-hybrid. Necessary for peroxisome biogenesis. The PEX4 and PEX22 pair may be important during the remodeling of peroxisome matrix contents as glyoxysomes transition to leaf peroxisomes.

UniProt Comments
Required for peroxisome biogenesis. Necessary for the developmental elimination of obsolete peroxisome matrix proteins. May be involved in the ubiquitination of PEX5, targeting it for recycling. Accepts the ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins.
