Anti-OPA3 Antibody Picoband® fluoro488 Vervoeging

Optic atrophy 3 protein is a protein that in humans is encoded by the OPA3 gene. The mouse ortholog of this protein co-purifies with the mitochondrial inner membrane. Mutations in this gene have been shown to result in 3-methylglutaconic aciduria type III and autosomal dominant optic atrophy and cataract. Multiple transcript variants encoding different isoforms have been found for this gene.

Component of the SKA1 complex, a microtubule-binding subcomplex of the outer kinetochore that is essential for proper chromosome segregation (PubMed:17093495, PubMed:19289083, PubMed:23085020) . Required for timely anaphase onset during mitosis, when chromosomes undergo bipolar attachment on spindle microtubules leading to silencing of the spindle checkpoint (PubMed:17093495) . The SKA1 complex is a component of the kinetochore-microtubule interface and ly associates with microtubules as oligomeric assemblies (PubMed:19289083) . The complex facilitates the processive movement of microspheres along a microtubule in a depolymerization-coupled manner (PubMed:17093495, PubMed:19289083) . In the complex, it is required for SKA1 localization (PubMed:19289083) . Affinity for microtubules is synergistically enhanced in the presence of the ndc-80 complex and may allow the ndc-80 complex to track depolymerizing microtubules (PubMed:23085020) .
