May be involved in mitochondrial protein import by enhancing productive ribosome interactions with the outer mitochondrial membrane and blocks the inappropriate interaction of ribosomes translating non-secretory nascent polypeptides with translocation sites in the membrane of the endoplasmic reticulum. EGD2 may also be involved in transcription regulation (By similarity). Predominantly cytoplasmic, may also transiently localize to the nucleus. Belongs to the NAC-alpha family.
