Summaries for MDH1 Gene

Entrez Gene Summary for MDH1 Gene

  • This gene encodes an enzyme that catalyzes the NAD/NADH-dependent, reversible oxidation of malate to oxaloacetate in many metabolic pathways, including the citric acid cycle. Two main isozymes are known to exist in eukaryotic cells: one is found in the mitochondrial matrix and the other in the cytoplasm. This gene encodes the cytosolic isozyme, which plays a key role in the malate-aspartate shuttle that allows malate to pass through the mitochondrial membrane to be transformed into oxaloacetate for further cellular processes. Alternatively spliced transcript variants have been found for this gene. A recent study showed that a C-terminally extended isoform is produced by use of an alternative in-frame translation termination codon via a stop codon readthrough mechanism, and that this isoform is localized in the peroxisomes. Pseudogenes have been identified on chromosomes X and 6. [provided by RefSeq, Feb 2016]

GeneCards Summary for MDH1 Gene

MDH1 (Malate Dehydrogenase 1) is a Protein Coding gene. Diseases associated with MDH1 include Retinitis Pigmentosa 28 and X-Linked Sideroblastic Anemia With Ataxia. Among its related pathways are Citrate cycle (TCA cycle) and Metabolism. GO annotations related to this gene include oxidoreductase activity and oxidoreductase activity, acting on the CH-OH group of donors, NAD or NADP as acceptor. An important paralog of this gene is MDH1B.
