    Summary
    The protein encoded by this gene is a Krebs tricarboxylic acid cycle enzyme that catalyzes the synthesis of citrate from oxaloacetate and acetyl coenzyme A. The enzyme is found in nearly all cells capable of oxidative metablism. This protein is nuclear encoded and transported into the mitochondrial matrix, where the mature form is found.

    10. Data suggest that METTL12, localized in mitochondrial matrix, modifies/methylates Lys368 of citrate synthase in external surface region close to its catalytic site; addition/removal of methylation has no effect on citrate synthase activity; Lys368 occurs in highly conserved sequence of amino acid residues of citrate synthase. (METTL12 = methyltransferase-like protein 12)

    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.
