CC -!- FUNCTION: Part of the endoplasmic reticulum membrane protein complex
CC (EMC) that enables the energy-independent insertion into endoplasmic
CC reticulum membranes of newly synthesized membrane proteins.
CC Preferentially accommodates proteins with transmembrane domains that
CC are weakly hydrophobic or contain destabilizing features such as
CC charged and aromatic residues. Involved in the cotranslational
CC insertion of multi-pass membrane proteins in which stop-transfer
CC membrane-anchor sequences become ER membrane spanning helices. It is
CC also required for the post-translational insertion of tail-anchored/TA
CC proteins in endoplasmic reticulum membranes. By mediating the proper
CC cotranslational insertion of N-terminal transmembrane domains in an N-
CC exo topology, with translocated N-terminus in the lumen of the ER,
CC controls the topology of multi-pass membrane proteins. By regulating
CC the insertion of various proteins in membranes, it is indirectly
CC involved in many cellular processes. {ECO:0000250|UniProtKB:Q15006}.
CC -!- SUBUNIT: Component of the ER membrane protein complex (EMC).
CC {ECO:0000250|UniProtKB:Q15006}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000250|UniProtKB:Q15006}; Peripheral membrane protein
CC {ECO:0000250|UniProtKB:Q15006}; Cytoplasmic side
CC {ECO:0000250|UniProtKB:Q15006}.
CC -!- SIMILARITY: Belongs to the EMC2 family. {ECO:0000305}.
