Anti-TARBP2 subunit of RISC loading complex antibodies are used for the immunodetection of the protein encoded by the TARBP2 gene. In humans, the canonical protein has a reported length of 366 amino acid residues and a mass of 39 kDa. Its subcellular localization is in the nucleus and cytoplasm. A member of the TARBP2 protein family, it is known to be required for formation of the RNA induced silencing complex (RISC). Other names for this target antigen include TRBP, TRBP1, TRBP2, RISC-loading complex subunit TARBP2, TAR (HIV) RNA-binding protein 2, and LOQS. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
