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 (PubMed:2644273, PubMed:7615509, PubMed:10206957,
CC PubMed:11058593). Specifically cleaves N-terminal signal peptides that
CC contain a hydrophobic alpha-helix (h-region) shorter than 18-20 amino
CC acids (By similarity). {ECO:0000250|UniProtKB:P67812,
CC ECO:0000269|PubMed:10206957, ECO:0000269|PubMed:11058593,
CC ECO:0000269|PubMed:2644273, ECO:0000269|PubMed:7615509}.
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:0000269|PubMed:10206957};
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 (PubMed:1846444, PubMed:9148931). The complex induces a local
CC thinning of the ER membrane which is used to measure the length of the
CC signal peptide (SP) h-region of protein substrates (By similarity).
CC This ensures the selectivity of the complex towards h-regions shorter
CC than 18-20 amino acids (By similarity). Interacts with SPC3
CC (PubMed:10206957). SPC associates with the translocon complex
CC (PubMed:1846444, PubMed:9148931). {ECO:0000250|UniProtKB:P67812,
CC ECO:0000269|PubMed:10206957, ECO:0000269|PubMed:1846444,
CC ECO:0000269|PubMed:9148931}.
CC -!- INTERACTION:
CC P15367; P46965: SPC1; NbExp=4; IntAct=EBI-16513, EBI-17823;
CC P15367; Q12133: SPC3; NbExp=3; IntAct=EBI-16513, EBI-17829;
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000269|PubMed:10206957, ECO:0000269|PubMed:14562095,
CC ECO:0000269|PubMed:2644273}; Single-pass type II membrane protein
CC {ECO:0000269|PubMed:10206957, ECO:0000269|PubMed:14562095,
CC ECO:0000269|PubMed:2644273}.
CC -!- DOMAIN: The C-terminal short (CTS) helix is essential for catalytic
CC activity (By similarity). It may be accommodated as a transmembrane
CC helix in the thinned membrane environment of the complex, similarly to
CC the signal peptide in the complex substrates (By similarity).
CC {ECO:0000250|UniProtKB:P67812}.
CC -!- PTM: N-glycosylated. {ECO:0000269|PubMed:10206957}.
CC -!- DISRUPTION PHENOTYPE: Leads to accumulation of core-glycosylated
CC glycoprotein precursors. {ECO:0000269|PubMed:3283143}.
CC -!- MISCELLANEOUS: Present with 3150 molecules/cell in log phase SD medium.
CC {ECO:0000269|PubMed:14562106}.
CC -!- SIMILARITY: Belongs to the peptidase S26B family. {ECO:0000305}.
