Summary
The protein encoded by this gene is an inner mitochondrial membrane scaffold protein. Absence of the encoded protein affects the structural integrity of mitochondrial cristae and leads to reductions in ATP production, cell growth, and oxygen consumption. This protein is part of the mitochondrial contact site and cristae organizing system (MICOS). Several transcript variants encoding different isoforms have been found for this gene.

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

    Description
    Transcript Variant: This variant (3) differs in the 3' UTR and coding sequence and lacks an alternate in-frame exon compared to variant 1. The resulting isoform (3) has a shorter and distinct C-terminus and lacks an internal segment compared to isoform 1.

RNA

  1. NR_133671.2 RNA Sequence

    Status: REVIEWED

    Description
    Transcript Variant: This variant (4) lacks an alternate exon but contains three additional alternate exons compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
