CC -!- FUNCTION: Component of the signal peptidase complex (SPC) which
CC catalyzes the cleavage of N-terminal signal sequences from nascent
CC proteins as they are translocated into the lumen of the endoplasmic
CC reticulum. Enhances the enzymatic activity of SPC and facilitates the
CC interactions between different components of the translocation site.
CC {ECO:0000250|UniProtKB:Q04969}.
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:P67812,
CC ECO:0000250|UniProtKB:Q04969}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000269|PubMed:16823372}; Multi-pass membrane protein
CC {ECO:0000269|PubMed:16823372}.
CC -!- SIMILARITY: Belongs to the SPCS2 family. {ECO:0000305}.
