Anti-YJU2 splicing factor homolog B antibodies are used for the immunodetection of the protein encoded by the YJU2B gene. In humans, the canonical protein has a reported length of 396 amino acid residues and a mass of 44.8 kDa. Its subcellular localization is in the nucleus. A member of the CWC16 protein family, it is suspected to be involved in mRNA splicing. Other names for this target antigen include 9 kDa protein, coiled-coil domain containing 130, coiled-coil domain-containing protein 130, and probable splicing factor YJU2B. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
