ab181873 Anti-MDH2 antibody [EPR14882(B)] was shown to specifically react with MDH2 in wild-type HEK293T cells. Loss of signal was observed when knockout cell line ab266449 (knockout cell lysate ab257533) was used. Wild-type and MDH2 knockout samples were subjected to SDS-PAGE. ab181873 and Anti-alpha Tubulin antibody [DM1A] - Loading Control (ab7291) were incubated overnight at 4°C at 1 in 1000 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.

Supplementary information

MDH2 also known as malate dehydrogenase 2 or mitochondrial malate dehydrogenase is an enzyme with a molecular mass of approximately 35 kDa. This enzyme catalyzes the conversion of malate to oxaloacetate using NAD+ as a cofactor. It is predominantly expressed in the mitochondria where it plays an important role in cellular respiration. The enzyme enables the malate dehydrogenase reaction which is key for the functioning of the tricarboxylic acid cycle.
Biological function summary

MDH2 participates in the critical process of energy production within the cell. While it does not form a complex itself its activity is intimately connected with other enzymes in mitochondrial energy metabolism. The malate dehydrogenase assay often measures the activity of MDH2 to understand the metabolic status of cells. By facilitating the oxidation of malate MDH2 aids in maintaining the efficiency of the mitochondrial electron transport chain by regenerating NADH.

Pathways

The enzyme is essential in the tricarboxylic acid (TCA) cycle and the malate-aspartate shuttle. In the TCA cycle MDH2 collaborates with enzymes like citrate synthase and isocitrate dehydrogenase to assist in the conversion of acetyl-CoA into energy-rich molecules. The malate-aspartate shuttle on the other hand involves MDH2 working closely with aspartate transaminase to transfer reducing equivalents into the mitochondria. These pathways highlight MDH2’s importance in cellular energy homeostasis.

Mutations or dysregulation in MDH2 have connections to certain metabolic conditions and cancers. For example alterations in MDH2 activity might contribute to conditions like mitochondrial myopathy altering energy metabolism. Moreover MDH2 is associated with NADH-producing enzymes whose dysregulation can support oncogenic pathways in cancer. Understanding these associations helps researchers pursue therapeutic targets that modulate MDH2 activity.
