    Summary
    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. 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.

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

    1. NM_001316877.1 → NP_001303806.1  malate dehydrogenase, peroxisomal isoform Mdh1x

      Status: REVIEWED

      Description
      Transcript Variant: This transcript (1) encodes two isoforms, which result from the use of alternative in-frame translation termination codons. The shorter isoform (Mdh1) results from translation termination at the upstream UGA stop codon, while the longer isoform (Mdh1x) results from UGA stop codon readthrough to the downstream UGA termination codon. This RefSeq represents the longer, C-terminally extended isoform (Mdh1x), which is localized in the peroxisomes. As the UGA stop codon has been reported to specify several alternative amino acids (tryptophan, cysteine, arginine and serine), its location in the longer isoform is denoted by an 'X'.
