Summary
Enables calcium ion binding activity; calcium ion sensor activity; and protein heterodimerization activity. Involved in calcium import into the mitochondrion; cellular response to calcium ion; and negative regulation of mitochondrial calcium ion concentration. Located in mitochondrial intermembrane space. Part of uniplex complex. Is active in mitochondrial inner membrane. [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.
