Entrez Gene Summary for OPA1 Gene

  • The protein encoded by this gene is a nuclear-encoded mitochondrial protein with similarity to dynamin-related GTPases. The encoded protein localizes to the inner mitochondrial membrane and helps regulate mitochondrial stability and energy output. This protein also sequesters cytochrome c. Mutations in this gene have been associated with optic atrophy type 1, which is a dominantly inherited optic neuropathy resulting in progressive loss of visual acuity, leading in many cases to legal blindness.

GeneCards Summary for OPA1 Gene

OPA1 (OPA1 Mitochondrial Dynamin Like GTPase) is a Protein Coding gene. Diseases associated with OPA1 include Optic Atrophy With Or Without Deafness, Ophthalmoplegia, Myopathy, Ataxia, And Neuropathy and Optic Atrophy 1. Among its related pathways are CDK-mediated phosphorylation and removal of Cdc6 and Glucose / Energy Metabolism. Gene Ontology (GO) annotations related to this gene include GTP binding and magnesium ion binding. An important paralog of this gene is DNM2.

UniProtKB/Swiss-Prot Summary for OPA1 Gene

  • Dynamin-related GTPase that is essential for normal mitochondrial morphology by regulating the equilibrium between mitochondrial fusion and mitochondrial fission (PubMed:16778770, PubMed:17709429, PubMed:20185555, PubMed:24616225, PubMed:28746876). Coexpression of isoform 1 with shorter alternative products is required for optimal activity in promoting mitochondrial fusion (PubMed:17709429). Binds lipid membranes enriched in negatively charged phospholipids, such as cardiolipin, and promotes membrane tubulation (PubMed:20185555). The intrinsic GTPase activity is low, and is strongly increased by interaction with lipid membranes (PubMed:20185555). Plays a role in remodeling cristae and the release of cytochrome c during apoptosis (By similarity). Proteolytic processing in response to intrinsic apoptotic signals may lead to disassembly of OPA1 oligomers and release of the caspase activator cytochrome C (CYCS) into the mitochondrial intermembrane space (By similarity). Plays a role in mitochondrial genome maintenance (PubMed:20974897, PubMed:18158317).
  • [Dynamin-like 120 kDa protein, form S1]: Inactive form produced by cleavage at S1 position by OMA1 following stress conditions that induce loss of mitochondrial membrane potential, leading to negative regulation of mitochondrial fusion.
  • Isoforms that contain the alternative exon 4b (present in isoform 4 and isoform 5) are required for mitochondrial genome maintenance, possibly by anchoring the mitochondrial nucleoids to the inner mitochondrial membrane.

OPA1_HUMAN
  • Optic atrophy 1 (OPA1) [MIM:165500]: A condition that features progressive visual loss in association with optic atrophy. Atrophy of the optic disk indicates a deficiency in the number of nerve fibers which arise in the retina and converge to form the optic disk, optic nerve, optic chiasm and optic tracts. OPA1 is characterized by an insidious onset of visual impairment in early childhood with moderate to severe loss of visual acuity, temporal optic disk pallor, color vision deficits, and centrocecal scotoma of variable density. {ECO:0000269 PubMed:11017079, ECO:0000269 PubMed:11017080, ECO:0000269 PubMed:11440988, ECO:0000269 PubMed:11440989, ECO:0000269 PubMed:11810270, ECO:0000269 PubMed:12036970, ECO:0000269 PubMed:12566046, ECO:0000269 PubMed:14961560, ECO:0000269 PubMed:15948788, ECO:0000269 PubMed:16513463, ECO:0000269 PubMed:16617242, ECO:0000269 PubMed:18204809, ECO:0000269 PubMed:18360822, ECO:0000269 PubMed:19319978, ECO:0000269 PubMed:19325939, ECO:0000269 PubMed:19969356, ECO:0000269 PubMed:20185555, ECO:0000269 PubMed:22382025, ECO:0000269 PubMed:22857269, ECO:0000269 PubMed:23401657}. Note=The disease is caused by variants affecting the gene represented in this entry.
  • Dominant optic atrophy plus syndrome (DOA+) [MIM:125250]: A neurologic disorder characterized most commonly by an insidious onset of visual loss and sensorineural hearing loss in childhood with variable presentation of other clinical manifestations including progressive external ophthalmoplegia, muscle cramps, hyperreflexia, and ataxia. There appears to be a wide range of intermediate phenotypes. {ECO:0000269 PubMed:15531309, ECO:0000269 PubMed:16240368, ECO:0000269 PubMed:18065439, ECO:0000269 PubMed:18158317, ECO:0000269 PubMed:18195150, ECO:0000269 PubMed:20185555, ECO:0000269 PubMed:21112924, ECO:0000269 PubMed:23387428}. Note=The disease is caused by variants affecting the gene represented in this entry.
  • Behr syndrome (BEHRS) [MIM:210000]: An autosomal recessive syndrome characterized by optic atrophy beginning in early childhood associated with ataxia, pyramidal signs, spasticity, mental retardation, and posterior column sensory loss. The ataxia, spasticity, and muscle contractures, mainly of the hip adductors, hamstrings, and soleus, are progressive and become more prominent in the second decade. {ECO:0000269 PubMed:21636302, ECO:0000269 PubMed:25012220, ECO:0000269 PubMed:25146916}. Note=The disease is caused by variants affecting the gene represented in this entry.
  • Mitochondrial DNA depletion syndrome 14, cardioencephalomyopathic type (MTDPS14) [MIM:616896]: An autosomal recessive mitochondrial disorder characterized by lethal infantile encephalopathy, hypertrophic cardiomyopathy and optic atrophy. Skeletal muscle biopsies show significant mtDNA depletion and abnormal mitochondria. {ECO:0000269 PubMed:26561570}. Note=The disease is caused by variants affecting the gene represented in this entry.
