Genes affected

EMC3 (HGNC:23999): (ER membrane protein complex subunit 3) Contributes to membrane insertase activity. Involved in protein insertion into ER membrane by stop-transfer membrane-anchor sequence and tail-anchored membrane protein insertion into ER membrane. Is integral component of endoplasmic reticulum membrane. Part of EMC complex. [provided by Alliance of Genome Resources, Apr 2022]
