Anti-CETN1 antibodies are used in the immunodetection of the protein centrin 1. In humans, the canonical protein has a reported length of 172 amino acid residues and a mass of 19.6 kDa. Its subcellular localization is in the cytoplasm. It is notably expressed in the testis. A member of the Centrin protein family, CETN1 is known to play a fundamental role in microtubule-organizing center structure and function. Synonyms for this target antigen include CETN, EF-hand protein, calcium binding protein, caltractin, centrin, EF-hand protein, 1, and CEN1. CETN1 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Over 60 citations in the literature describe the use of CETN1 antibodies in research. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
