CC -!- FUNCTION: Component of the microsomal signal peptidase complex which CC removes signal peptides and other N-terminal peptides from nascent CC proteins as they are translocated into the lumen of the endoplasmic CC reticulum. {ECO:0000250|UniProtKB:P61009}. CC -!- SUBUNIT: Complex of five different proteins: SEC11A, SEC11C, spcs- CC 1/SPCS1, spcs-2/SPCS2 and spcs-3/SPCS3. {ECO:0000250|UniProtKB:P61008}. CC -!- SUBCELLULAR LOCATION: Microsome membrane CC {ECO:0000250|UniProtKB:P61008}; Single-pass type II membrane protein CC {ECO:0000305}. Endoplasmic reticulum membrane CC {ECO:0000250|UniProtKB:Q12133}; Single-pass type II membrane protein CC {ECO:0000305}. CC -!- SIMILARITY: Belongs to the SPCS3 family. {ECO:0000305}.
