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 like the G
CC       protein-coupled receptors. By regulating the insertion of various
CC       proteins in membranes, it is indirectly involved in many cellular
CC       processes. {ECO:0000250|UniProtKB:Q9BV81}.
CC   -!- SUBUNIT: Component of the ER membrane protein complex (EMC).
CC       {ECO:0000250|UniProtKB:Q9BV81}.
CC   -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC       {ECO:0000250|UniProtKB:Q9BV81}; Multi-pass membrane protein
CC       {ECO:0000250|UniProtKB:Q9BV81}.
CC   -!- SIMILARITY: Belongs to the EMC6 family. {ECO:0000305}.
