Complex II subunit 70 kDa Fp monoclonal antibody

Catalog No. MS204

$355.00 - 100 µg

UniProt Number: P31040
Alternate Names: Succinate dehydrogenase [ubiquinone] flavoprotein subunit, Flavoprotein subunit of complex II, Fp, SDHA, SDH2, SDHF
Structure and Function: Flavoprotein (Fp) is a subunit (664 AA) of the succinate dehydrogenase enzyme, which is a component of Complex II of the ETC. Succinate dehydrogenase transfers electrons from succinate to coenzyme Q (ubiquinone).
Disease Associations: Abnormalities of the flavoprotein subunit are associated with complex II mitochondrial respiratory chain deficiency and succinate CoQ reductase deficiency, which can cause a wide range of pathological disorders affecting individual organs or entire body systems. In rare cases, a deficit in complex II can cause mitochondrial encephalomyopathy, leukodystrophy, late-onset optic atrophy and ataxia, myopathy with exercise intolerance, and isolated cardiomyopathy. Leigh syndrome is a pathology associated specifically with the flavoprotein subunit (SdhA) of succinate dehydrogenase. This syndrome presents itself with necrotic lesions that are located symmetrically in both sides the subcortical brain.
