Automated description from the Alliance of Genome Resources
Exhibits calcium ion binding activity and protein heterodimerization activity. Predicted to be involved in several processes, including calcium import into the mitochondrion; positive regulation of mitochondrial calcium ion concentration; and regulation of cellular hyperosmotic salinity response. Localizes to the calcium channel complex and mitochondrial intermembrane space. Human ortholog(s) of this gene implicated in myopathy with extrapyramidal signs. Is expressed in brain; heart; liver; and lung. Orthologous to human MICU1 (mitochondrial calcium uptake 1).
