Anti-CCDC109B antibodies enable researchers to detect and measure the CCDC109B antigen in biological samples. This target is a reported synonym of the MCUB gene, which encodes mitochondrial calcium uniporter dominant negative subunit beta. This protein is reported to negatively regulate the activity of MCU, the mitochondrial inner membrane calcium uniporter, and thereby modulates calcium uptake into the mitochondrion. The human version of CCDC109B has a canonical amino acid length of 336 residues and a protein mass of 39.1 kilodaltons. It is reported to be localized in the mitochondria of cells and notably expressed in many tissues, such as the bone marrow, tonsil, and appendix. This target antigen may also be known as calcium uniporter regulatory subunit MCUb, mitochondrial. Indicated applications for CCDC109B antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
