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 (By similarity).
CC {ECO:0000250|UniProtKB:P15367, ECO:0000250|UniProtKB:P67812}.
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:0000250|UniProtKB:P15367};
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 (By
CC similarity). {ECO:0000250|UniProtKB:P15367,
CC ECO:0000250|UniProtKB:P67812}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000250|UniProtKB:P15367}; Single-pass type II membrane protein
CC {ECO:0000250|UniProtKB:P15367}.
CC -!- DOMAIN: The C-terminal short (CTS) helix is essential for catalytic
CC activity. It may be accommodated as a transmembrane helix in the
CC thinned membrane environment of the complex, similarly to the signal
CC peptide in the complex substrates. {ECO:0000250|UniProtKB:P67812}.
CC -!- SIMILARITY: Belongs to the peptidase S26B family. {ECO:0000305}.
