Immunogen

The exact immunogen used to generate this antibody is proprietary information.

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.

Supplementary information

OPA1 also known as optic atrophy 1 is a dynamin-related GTPase protein important for mitochondrial fusion. OPA1 has a molecular weight of about 120 kDa and is present mostly in the inner mitochondrial membrane. It promotes the maintenance of mitochondrial DNA cristae structures and the modulation of mitochondrial dynamics. Expression of OPA1 occurs in tissues with high energy demands including the retina brain and muscles. Detection of the OPA1 protein can be done using techniques such as Western blot and it reveals different isoforms generated through alternative splicing.
Biological function summary

Mitochondrial dynamics involving OPA1 ensure energy production efficiency and cell health. OPA1 plays a role in mitochondrial fusion by forming a complex with mitofusins MFN1 and MFN2. This complex maintains the integrity of mitochondrial networks facilitates proper respiratory function and prevents apoptosis by regulating cristae junctions. It also participates in the stress response particularly in the preservation of the mitochondrial structure and function under challenging conditions.

Pathways

OPA1 integrates into the mitochondrial fusion and fission pathways important for cellular energy metabolism. It works alongside proteins like DRP1 in balancing these processes. The involvement in these pathways is essential for cellular adaptation to metabolic needs and stress. OPA1 also has a relationship with the PINK1/Parkin pathway where its regulation affects mitophagy a process of clearing damaged mitochondria. These interactions highlight the importance of OPA1 in maintaining cellular and mitochondrial homeostasis.

Mutations in OPA1 have been linked to autosomal dominant optic atrophy and a range of neurodegenerative conditions. The protein’s dysfunction leads to the degeneration of the retinal ganglion cells and their axons resulting in vision loss. OPA1 also shows connections to disorders like Charcot-Marie-Tooth disease where its interaction with other proteins like MFN2 plays a role. Deficiency or dysfunction of OPA1 disrupts mitochondrial dynamics leading to cellular energy deficits and contributing to disease pathophysiology.

Target data

Dynamin-related GTPase that is essential for normal mitochondrial morphology by mediating fusion of the mitochondrial inner membranes, regulating cristae morphology and maintaining respiratory chain function (PubMed : 16778770, PubMed : 17709429, PubMed : 20185555, PubMed : 24616225, PubMed : 28628083, PubMed : 28746876, PubMed : 31922487, PubMed : 32228866, PubMed : 32567732, PubMed : 33130824, PubMed : 33237841, PubMed : 37612504, PubMed : 37612506). Exists in two forms : the transmembrane, long form (Dynamin-like GTPase OPA1, long form; L-OPA1), which is tethered to the inner mitochondrial membrane, and the short soluble form (Dynamin-like GTPase OPA1, short form; S-OPA1), which results from proteolytic cleavage and localizes in the intermembrane space (PubMed : 31922487, PubMed : 32228866, PubMed : 33237841, PubMed : 37612504, PubMed : 37612506). Both forms (L-OPA1 and S-OPA1) cooperate to catalyze the fusion of the mitochondrial inner membrane (PubMed : 31922487, PubMed : 37612504, PubMed : 37612506). The equilibrium between L-OPA1 and S-OPA1 is essential : excess levels of S-OPA1, produced by cleavage by OMA1 following loss of mitochondrial membrane potential, lead to an impaired equilibrium between L-OPA1 and S-OPA1, inhibiting mitochondrial fusion (PubMed : 20038677, PubMed : 31922487). The balance between L-OPA1 and S-OPA1 also influences cristae shape and morphology (By similarity). Involved in remodeling cristae and the release of cytochrome c during apoptosis (By similarity). Proteolytic processing by PARL 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). Acts as a regulator of T-helper Th17 cells, which are characterized by cells with fused mitochondria with tight cristae, by mediating mitochondrial membrane remodeling : OPA1 is required for interleukin-17 (IL-17) production (By similarity). Its role in mitochondrial morphology is required for mitochondrial genome maintenance (PubMed : 18158317, PubMed : 20974897).. Dynamin-like GTPase OPA1, long form. Constitutes the transmembrane long form (L-OPA1) that plays a central role in mitochondrial inner membrane fusion and cristae morphology (PubMed : 31922487, PubMed : 32228866, PubMed : 37612504, PubMed : 37612506). L-OPA1 and the soluble short form (S-OPA1) form higher-order helical assemblies that coordinate the fusion of mitochondrial inner membranes (PubMed : 31922487, PubMed : 37612504, PubMed : 37612506). Inner membrane-anchored L-OPA1 molecules initiate membrane remodeling by recruiting soluble S-OPA1 to rapidly polymerize into a flexible cylindrical scaffold encaging the mitochondrial inner membrane (PubMed : 37612504, PubMed : 37612506). Once at the membrane surface, the formation of S-OPA1 helices induce bilayer curvature (PubMed : 37612504, PubMed : 37612506). OPA1 dimerization through the paddle region, which inserts into cardiolipin-containing membrane, promotes GTP hydrolysis and the helical assembly of a flexible OPA1 lattice on the membrane, which drives membrane curvature and mitochondrial fusion (PubMed : 28628083, PubMed : 37612504, PubMed : 37612506). Plays a role in the maintenance and remodeling of mitochondrial cristae, some invaginations of the mitochondrial inner membrane that provide an increase in the surface area (PubMed : 32567732, PubMed : 33130824). Probably acts by forming helical filaments at the inside of inner membrane tubes with the shape and dimensions of crista junctions (By similarity). The equilibrium between L-OPA1 and S-OPA1 influences cristae shape and morphology : increased L-OPA1 levels promote cristae stacking and elongated mitochondria, while increased S-OPA1 levels correlated with irregular cristae packing and round mitochondria shape (By similarity).. Dynamin-like GTPase OPA1, short form. Constitutes the soluble short form (S-OPA1) generated by cleavage by OMA1, which plays a central role in mitochondrial inner membrane fusion and cristae morphology (PubMed : 31922487, PubMed : 32228866, PubMed : 32245890, PubMed : 37612504, PubMed : 37612506). The transmembrane long form (L-OPA1) and the S-OPA1 form higher-order helical assemblies that coordinate the fusion of mitochondrial inner membranes (PubMed : 31922487, PubMed : 32228866, PubMed : 37612504, PubMed : 37612506). Inner membrane-anchored L-OPA1 molecules initiate membrane remodeling by recruiting soluble S-OPA1 to rapidly polymerize into a flexible cylindrical scaffold encaging the mitochondrial inner membrane (PubMed : 32228866, PubMed : 37612504, PubMed : 37612506). Once at the membrane surface, the formation of S-OPA1 helices induce bilayer curvature (PubMed : 37612504, PubMed : 37612506). OPA1 dimerization through the paddle region, which inserts into cardiolipin-containing membrane, promotes GTP hydrolysis and the helical assembly of a flexible OPA1 lattice on the membrane, which drives membrane curvature and mitochondrial fusion (PubMed : 28628083, PubMed : 37612504, PubMed : 37612506). Excess levels of S-OPA1 produced by cleavage by OMA1 following stress conditions that induce loss of mitochondrial membrane potential, lead to an impaired equilibrium between L-OPA1 and S-OPA1, thereby inhibiting mitochondrial fusion (PubMed : 20038677). Involved in mitochondrial safeguard in response to transient mitochondrial membrane depolarization by mediating flickering : cleavage by OMA1 leads to excess production of S-OPA1, preventing mitochondrial hyperfusion (By similarity). Plays a role in the maintenance and remodeling of mitochondrial cristae, some invaginations of the mitochondrial inner membrane that provide an increase in the surface area (PubMed : 32245890). Probably acts by forming helical filaments at the inside of inner membrane tubes with the shape and dimensions of crista junctions (By similarity). The equilibrium between L-OPA1 and S-OPA1 influences cristae shape and morphology : increased L-OPA1 levels promote cristae stacking and elongated mitochondria, while increased S-OPA1 levels correlated with irregular cristae packing and round mitochondria shape (By similarity).. Isoform 1. Coexpression of isoform 1 with shorter alternative products is required for optimal activity in promoting mitochondrial fusion.. Isoform 4. Isoforms that contain the alternative exon 4b are required for mitochondrial genome maintenance, possibly by anchoring the mitochondrial nucleoids to the inner mitochondrial membrane.. Isoform 5. Isoforms that contain the alternative exon 4b are required for mitochondrial genome maintenance, possibly by anchoring the mitochondrial nucleoids to the inner mitochondrial membrane.
