This gene encodes an outer mitochondrial membrane protein that functions in the regulation of mitochondrial morphology. It can directly recruit the fission mediator dynamin-related protein 1 (Drp1) to the mitochondrial surface. The gene is located within the Smith-Magenis syndrome region on chromosome 17.

Entrez Gene Summary for MIEF2 Gene

  • This gene encodes an outer mitochondrial membrane protein that functions in the regulation of mitochondrial morphology. It can directly recruit the fission mediator dynamin-related protein 1 (Drp1) to the mitochondrial surface. The gene is located within the Smith-Magenis syndrome region on chromosome 17. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jun 2011]

GeneCards Summary for MIEF2 Gene

MIEF2 (Mitochondrial Elongation Factor 2) is a Protein Coding gene. Diseases associated with MIEF2 include Combined Oxidative Phosphorylation Deficiency 49 and Smith-Magenis Syndrome. An important paralog of this gene is MIEF1.

UniProtKB/Swiss-Prot Summary for MIEF2 Gene

  • Mitochondrial outer membrane protein which regulates mitochondrial organization (PubMed:29361167). It is required for mitochondrial fission and promotes the recruitment and association of the fission mediator dynamin-related protein 1 (DNM1L) to the mitochondrial surface independently of the mitochondrial fission FIS1 and MFF proteins. Regulates DNM1L GTPase activity.
