    Summary
    Enables calcium:proton antiporter activity. Involved in calcium export from the mitochondrion; mitochondrial calcium ion homeostasis; and protein complex oligomerization. Located in mitochondrial inner membrane. Is expressed in brain; embryo; gonad; liver; and seminiferous cord. Orthologous to human LETM1 (leucine zipper and EF-hand containing transmembrane protein 1). [provided by Alliance of Genome Resources, Dec 2024]

    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.
