CC -!- FUNCTION: Catalytic component of the signal peptidase complex (SPC)
CC which catalyzes the cleavage of N-terminal signal sequences from
CC nascent proteins as they are translocated into the lumen of the
CC endoplasmic reticulum (By similarity). Specifically cleaves N-terminal
CC signal peptides that contain a hydrophobic alpha-helix (h-region)
CC shorter than 18-20 amino acids. {ECO:0000256|ARBA:ARBA00029411}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Cleavage of hydrophobic, N-terminal signal or leader sequences
CC from secreted and periplasmic proteins.; EC=3.4.21.89;
CC Evidence={ECO:0000256|ARBA:ARBA00000677};
CC -!- SUBUNIT: Component of the signal peptidase complex (SPC) composed of a
CC catalytic subunit SEC11 and three accessory subunits SPC1, SPC2 and
CC SPC3 (By similarity). The complex induces a local thinning of the ER
CC membrane which is used to measure the length of the signal peptide (SP)
CC h-region of protein substrates. This ensures the selectivity of the
CC complex towards h-regions shorter than 18-20 amino acids (By
CC similarity). SPC associates with the translocon complex.
CC {ECO:0000256|ARBA:ARBA00029478}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000256|ARBA:ARBA00004648}; Single-pass type II membrane protein
CC {ECO:0000256|ARBA:ARBA00004648}. Membrane
CC {ECO:0000256|ARBA:ARBA00004606}; Single-pass type II membrane protein
CC {ECO:0000256|ARBA:ARBA00004606}.
CC -!- SIMILARITY: Belongs to the peptidase S26B family.
CC {ECO:0000256|ARBA:ARBA00011035}.
