Protein
Signal peptide peptidase 1
Organism
Oryza sativa subsp. japonica
Function
Intramembrane-cleaving aspartic protease (I-CLiP) that cleaves type II membrane signal peptides in the hydrophobic plane of the membrane. Catalyzes intramembrane proteolysis of some signal peptides after they have been cleaved from a preprotein, resulting in the release of the fragment from the ER membrane into the cytoplasm.
Similarity
Belongs to the peptidase A22B family.
