Enables calcium ion binding activity; calcium ion sensor activity; and protein heterodimerization activity. Involved in calcium import into the mitochondrion and positive regulation of cristae formation. Located in mitochondrial intermembrane space. Part of calcium channel complex. Is active in mitochondrial inner membrane. Is expressed in several structures, including genitourinary system; liver; nervous system; parathyroid gland; and respiratory system.
