Protein RALF-like 4; Cell signaling peptide that may regulate plant stress, growth, and development. Mediates a rapid alkalinization of extracellular space by mediating a transient increase in the cytoplasmic Ca(2+) concentration leading to a calcium-dependent signaling events through a cell surface receptor and a concomitant activation of some intracellular mitogen-activated protein kinases (By similarity).

Peroxisome biogenesis factor 10; Involved in the formation of peroxisomes, lipid bodies and protein bodies. Required for normal-shaped peroxisomes that can physically associate with the outer membrane of the chloroplast envelope. Not involved in beta-oxidation and glyoxylate cycle. Acts as an E3 ubiquitin-protein ligase. Belongs to the pex2/pex10/pex12 family.

Protein APEM9; Involved in peroxisome biogenesis and matrix protein import. Required for pollen maturation and in vivo germination via its role in peroxisomal function, which partially involves jasmonic acid biosynthesis. Transported to peroxisomes via the interaction with PEX19-1. Required for peroxisomal protein import by acting as an anchoring protein for the AAA ATPase complex, which consists of PEX1 and PEX6.

Peroxisome biogenesis protein 5; Import receptor for peroxisomal-targeting signal one (PTS1). A receptor-cargo complex composed of PEX5, PEX7, a PTS1-containing protein and a PTS2-containing protein is targeted to peroxisomes during import. Necessary for the developmental elimination of obsolete peroxisome matrix proteins.

Peroxisome biogenesis protein 7; Import receptor for peroxisomal-targeting signal two (PTS2). A receptor-cargo complex composed of PEX5, PEX7, a PTS1-containing protein and a PTS2-containing protein is targeted to peroxisomes during import. Belongs to the WD repeat peroxin-7 family.

Peroxisome biogenesis protein 16; Involved in the formation of peroxisomes, lipid bodies and protein bodies.

Peroxisomal membrane protein 13; Involved in PTS1- and PTS2-dependent protein import into peroxisomes. Required for PTS1- dependent protein import into pollen peroxisomes. Acts as a docking factor on peroxisomal membranes. Required for the proper targeting of PEX7 to the peroxisome. Required for the export/release of receptors on the peroxisome membrane. Essential for pollen-tube discharge that take place only in the presence of functional peroxisomes in either the male or the female gametophyte. Belongs to the peroxin-13 family.

Probable purine permease 7.

Glyoxysomal processing protease, glyoxysomal; Trypsin-like serine endopeptidase involved in the processing of glyoxysomal higher molecular weight precursor. The dimeric form carries out the specific cleavages needed to remove PTS2-containing presequences, whereas the monomeric form degrades the removed presequences and misfolded proteins (Probable). Not required for degradation of glyoxylate cycle enzymes during seedling development.
