CC -!- FUNCTION: Microsomal signal peptidase is a membrane-bound CC endoproteinase that removes signal peptides from nascent proteins CC as they are translocated into the lumen of the endoplasmic CC reticulum. {ECO:0000250}. CC -!- SUBUNIT: Complex of five different proteins: SEC11L1, SEC11L3, CC SPCS1, SPCS2 and SPCS3. {ECO:0000250}. CC -!- SUBCELLULAR LOCATION: Microsome membrane {ECO:0000305}; Single- CC pass type II membrane protein {ECO:0000305}. Endoplasmic reticulum CC membrane {ECO:0000305}; Single-pass type II membrane protein CC {ECO:0000305}. CC -!- SIMILARITY: Belongs to the SPCS3 family. {ECO:0000305}.
