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 (By similarity). CC -!- SUBUNIT: Complex of five different proteins: SEC11L1, SEC11L3, CC SPCS1, SPCS2 and SPCS3 (By similarity). CC -!- SUBCELLULAR LOCATION: Microsome; microsomal membrane; single-pass CC type II membrane protein (Potential). CC -!- SIMILARITY: Belongs to the SPCS3 family.
