Anti-CENATAC antibodies are used in the immunodetection of the protein centrosomal AT-AC splicing factor. In humans, the canonical protein has a reported length of 332 amino acid residues and a mass of 38 kDa. Its subcellular localization is in the cytoplasm. CENATAC is a known component of the minor spliceosome that promotes splicing of a specific, rare minor intron subtype. Post-translational modifications have been described, including acetylation. The CENATAC gene has been associated with the disease, Mosaic variegated aneuploidy syndrome. Synonyms for this target antigen include coiled-coil domain containing 84 and coiled-coil domain-containing protein 84. CENATAC gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
