Anti-Centrin 3 antibodies are used in the immunodetection of the protein encoded by the CETN3 gene. In humans, the canonical protein has a reported length of 167 amino acid residues and a mass of 19.6 kDa. Its subcellular localization is in the nucleus and cytoplasm. A member of the Centrin protein family, it is known to play a fundamental role in microtubule-organizing center structure and function; As a component of the TREX-2 complex, involved in the export of mRNAs to the cytoplasm through the nuclear pores. Other names for this target antigen include CEN3, CDC31 yeast homolog, EF-hand superfamily member, centrin, EF-hand protein, 3 (CDC31 homolog, yeast), and CDC31.
