Anti-copper metabolism (Murr1) domain containing 1 antibodies enable researchers to detect and measure the copper metabolism (Murr1) domain containing 1 antigen in biological samples. This target is a reported synonym of the COMMD1 gene, which encodes copper metabolism domain containing 1. This protein is known to function in protein transport, among other biological roles. The human version of copper metabolism (Murr1) domain containing 1 has a canonical amino acid length of 190 residues and a protein mass of 21.2 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus, cytoplasmic vesicles, and cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include COMM domain-containing protein 1 and copper metabolism (Murr1) domain containing 1.
