    Summary
    Predicted to enable mitochondrion targeting sequence binding activity and protein transmembrane transporter activity. Predicted to be involved in protein insertion into mitochondrial inner membrane. Located in mitochondrion. Is expressed in several structures, including alimentary system; brain; cardiovascular system; egg cylinder; and genitourinary system. Human ortholog(s) of this gene implicated in combined oxidative phosphorylation deficiency 43. Orthologous to human TIMM22 (translocase of inner mitochondrial membrane 22).

    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: VALIDATED

      Description
      Transcript Variant: This variant (3) differs in the 5' UTR, lacks part of the 5' coding region, and uses an alternate start codon, compared to variant 1. The encoded isoform (3) has a shorter and distinct N-terminus, compared to isoform 1.

      Status: VALIDATED

      Description
      Transcript Variant: This variant (2) is missing an exon in the coding region compared to transcript variant 1, which results in a frame-shift and a shorter isoform (2) with a distinct C-terminus compared to isoform 1. Variant 2 has transcript support, but the encoded isoform 2 is predicted, lacking in vivo protein support.

      Status: VALIDATED

      Description
      Transcript Variant: This variant (4) uses an alternate 5'terminal exon and an alternate splice site at an internal exon, compared to variant 1. This variant is represented as non-coding because the predicted protein does not meet RefSeq quality criteria.
