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. Teleost fish express two cytosolic isozymes: one is ubiquitously expressed and the other is expressed predominantly in the eye and skeletal muscle. This gene encodes the ubiquitously expressed isozyme. 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. A paralog of this gene is found on chromosome 1. [provided by RefSeq, Sep 2017]

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_001355543.1NP_001342472.1  malate dehydrogenase 1Ab, NAD (soluble) isoform mdh1x

    Status: REVIEWED

    Description
    Transcript Variant: This variant (1) represents the predominant transcript and 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 UAA 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'.

    Status: REVIEWED

    Description
    Transcript Variant: This variant (3) lacks an exon in the 5' region, which results in translation initiation at an in-frame downstream start codon compared to variant 1. The resulting isoform (3) has a shorter N-terminus compared to isoform mdh1.
