Part of the endoplasmic reticulum membrane protein complex that enables the energy-independent insertion into endoplasmic reticulum membranes of newly synthesized membrane proteins . Preferentially accommodates proteins with transmembrane domains that are weakly hydrophobic or contain destabilizing features such as charged and aromatic residues . Involved in the cotranslational insertion of multi-pass membrane proteins in which stop-transfer membrane-anchor sequences become ER membrane spanning helices . It is also required for the post-translational insertion of tail-anchored/TA proteins in endoplasmic reticulum membranes . By mediating the proper cotranslational insertion of N-terminal transmembrane domains in an N-exo topology, with translocated N-terminus in the lumen of the ER, controls the topology of multi-pass membrane proteins like the G protein-coupled receptors . By regulating the insertion of various proteins in membranes, it is indirectly involved in many cellular processes .
