Specificity
Recent lab testing showed that the antibody detects the band of interest at the proper molecular weight in several cell and tissue lysates. However, the antibody also detects a band at about 50kDa. We could not find in the literature any references on what this band could be. On our test, the 50kDa band detections decreased by decreasing the antibody concentration. -

Function
Dynamin-related GTPase required for mitochondrial fusion and regulation of apoptosis. May form a diffusion barrier for proteins stored in mitochondrial cristae. 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. -
Tissue specificity
Highly expressed in retina. Also expressed in brain, testis, heart and skeletal muscle. Isoform 1 expressed in retina, skeletal muscle, heart, lung, ovary, colon, thyroid gland, leukocytes and fetal brain. Isoform 2 expressed in colon, liver, kidney, thyroid gland and leukocytes. Low levels of all isoforms expressed in a variety of tissues. -
Involvement in disease
Defects in OPA1 are a cause of optic atrophy type 1 (OPA1) [MIM:165500]. OPA1 is a dominantly inherited optic neuropathy occurring in 1 in 50,000 individuals that features progressive loss in visual acuity leading, in many cases, to legal blindness.
Defects in OPA1 are the cause of optic atrophy 1 with deafness (OPA1D) [MIM:125250]. Some individuals with mutations in OPA1 manifest also ophthalmoplegia and myopathy. -
Sequence similarities
Belongs to the dynamin family. -
Post-translational
modificationsPARL-dependent proteolytic processing releases an antiapoptotic soluble form not required for mitochondrial fusion. -
Cellular localization
Mitochondrion inner membrane. Mitochondrion intermembrane space. - Information by UniProt
