Anti-CALM antibodies enable researchers to detect and measure the CALM antigen in biological samples. This target is a reported synonym of the CALM2 gene, which encodes calmodulin 2. This protein is known to function in GPCR signaling pathways, among other biological roles. The human version of CALM has a canonical amino acid length of 149 residues and a protein mass of 16.8 kilodaltons. It is reported to be localized in the cytoplasm of cells and widely expressed in many tissue types. CALM is a member of the Calmodulin protein family. A number of CALM antibodies have been mentioned in research publications and have associated citations. These antibodies are most commonly used in ELISA experiments, among other applications.
