part of endoplasmic reticulum membrane EMC complex https://github.com/geneontology/go-ontology/issues/13657 https://github.com/geneontology/go-ontology/issues/20234 mah Note that this complex used to be thought to be involved in ER-mitochondrial membrane tethering, which is required to facilitate lipid transfer from the ER to the mitochondrial membrane, but newer findings show that this was incorrect. 2011-01-19T06:16:53Z cellular_component ER membrane protein complex endoplasmic reticulum membrane protein complex A transmembrane protein complex located in the endoplasmic reticulum (ER) involved in the insertion of newly synthesized proteins in the membrane of the ER. In S. cerevisiae, it has six members: EMC1, EMC2, AIM27, EMC4, KRE27, and EMC6. GO:0072546 membrane protein complex endoplasmic reticulum protein-containing complex
