Mammalian mitochondrial ribosomal proteins are encoded by nuclear genes and help in protein synthesis within the mitochondrion. Mitochondrial ribosomes (mitoribosomes) consist of a small 28S subunit and a large 39S subunit. They have an estimated 75% protein to rRNA composition compared to prokaryotic ribosomes, where this ratio is reversed. Another difference between mammalian mitoribosomes and prokaryotic ribosomes is that the latter contain a 5S rRNA. Among different species, the proteins comprising the mitoribosome differ greatly in sequence, and sometimes in biochemical properties, which prevents easy recognition by sequence homology. This gene encodes a 39S subunit protein. Alternative splicing results in multiple transcript variants. Pseudogenes corresponding to this gene are found on chromosomes 6p and 12p. Read-through transcription also exists between this gene and the neighboring upstream lipoyltransferase 1 (LIPT1) gene. [provided by RefSeq, Mar 2011]

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.

    Status: REVIEWED

    Transcript Variant: This variant (3) differs in the 3' region, compared to variant 1. This transcript is predicted to be subject to nonsense-mediated decay (NMD), and therefore the coding sequence is not annotated on this record.

Suppressed Reference Sequence(s)

The following Reference Sequences have been suppressed. Explain

  1. NM_016503.2: Suppressed sequence

    NM_016503.2: This RefSeq was permanently suppressed because currently there is insufficient support for the transcript and the protein.
  2. NM_145213.2: Suppressed sequence

    NM_145213.2: This RefSeq was permanently suppressed because it is predicted to be subject to nonsense-mediated decay.
