Genes affected

MIEF1 (HGNC:25979): (mitochondrial elongation factor 1) Enables ADP binding activity; GDP binding activity; and identical protein binding activity. Involved in several processes, including positive regulation of mitochondrial fission; positive regulation of mitochondrial translation; and positive regulation of protein targeting to membrane. Located in mitochondrial matrix and mitochondrial outer membrane. Colocalizes with mitochondrial large ribosomal subunit. [provided by Alliance of Genome Resources, Apr 2022]
