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:Q9P0I2}. CC -!- SUBUNIT: Component of the ER membrane protein complex (EMC). CC {ECO:0000250|UniProtKB:Q9P0I2}. CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane CC {ECO:0000250|UniProtKB:Q9P0I2}; Multi-pass membrane protein CC {ECO:0000250|UniProtKB:Q9P0I2}. CC -!- TISSUE SPECIFICITY: Localized to the inner segment and synapse in CC photoreceptor cells. {ECO:0000269|PubMed:15716502}. CC -!- SIMILARITY: Belongs to the EMC3 family. {ECO:0000305}.
