Anti-CCDC109A antibodies enable researchers to detect and measure the CCDC109A antigen in biological samples. This target is a reported synonym of the MCU gene, which encodes mitochondrial calcium uniporter. This protein is known to function in carbohydrate metabolism and homeostasis, among other biological roles. The human version of CCDC109A has a canonical amino acid length of 351 residues and a protein mass of 39.9 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the mitochondria of cells and widely expressed in many tissue types. CCDC109A is a member of the MCU (TC 1.A.77) protein family.
