Summary
The protein encoded by this gene is found exclusively in the mitochondrion, where it catalyzes the transfer of a malonyl group from malonyl-CoA to the mitochondrial acyl carrier protein. The encoded protein may be part of a fatty acid synthase complex that is more like the type II prokaryotic and plastid complexes rather than the type I human cytosolic complex. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Mar 2012]

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.

RNA

  1. NR_046423.1 RNA Sequence

    Status: REVIEWED

    Description
    Transcript Variant: This variant (3) uses an alternate splice site in the 5' coding region, compared to variant 1, which results in a frameshift and an early stop codon. The transcript is sufficiently abundant to represent as a RefSeq record; however, the predicted protein is not represented because the product is significantly truncated and the transcript is a candidate for nonsense-mediated mRNA decay (NMD).
