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}.
