Anti-calumenin antibodies are used for the immunodetection of the protein encoded by the CALU gene. In humans, the canonical protein has a reported length of 315 amino acid residues and a mass of 37.1 kDa. Its subcellular localization is in the ER, Golgi, and is secreted. Alternative splicing is reported to yield 15 different isoforms for this protein. It is ubiquitously expressed across many tissue types. A member of the CREC protein family, it is known to be involved in regulation of vitamin K-dependent carboxylation of multiple N-terminal glutamate residues. Other names for this target antigen include crocalbin-like protein, multiple EF-hand protein, and IEF SSP 9302. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of calumenin antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
