    Summary
    This gene is a member of the mitochondrial carrier family which includes nuclear-encoded transporters localized on the inner mitochondrial membranes. Members of the family transport important small molecules across the mitochondrial inner membrane. This protein is involved in the transport of S-adenosylmethionine (SAM) into the mitochondria. Mutations in this gene are associated with combined oxidative phosphorylation deficiency 28. Alternative splicing results in multiple transcript variants encoding different isoforms.

    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.

      Transcript Variant: This variant (3) lacks an internal exon but includes an alternate internal exon, compared to variant 1. This variant is represented as non-coding because the use of the expected translational start codon, as used in variant 2, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).

    Suppressed Reference Sequence(s)

    The following Reference Sequences have been suppressed. Explain

    1. NM_001009938.1: Suppressed sequence

      Description
      NM_001009938.1: This RefSeq was permanently suppressed because it is a nonsense-mediated mRNA decay (NMD) candidate.

    2. NM_001350991.1: Suppressed sequence

      Description
      NM_001350991.1: This RefSeq was removed because currently there is insufficient support for the transcript.

    3. NM_001350992.1: Suppressed sequence

      Description
      NM_001350992.1: This RefSeq was removed because currently there is insufficient support for the transcript.
