Small inducible cytokine B11 precursor; small inducible cytokine subfamily B (Cys-X-Cys), member 9B; small inducible cytokine subfamily B (Cys-X-Cys), member 11. This protein is a CXC member of the chemokine superfamily. It induces a chemotactic response in activated T-cells and is the dominant ligand for CXC receptor-3. The gene encoding this protein contains 4 exons and at least three polyadenylation signals which might reflect cell-specific regulation of expression. IFN-gamma is a potent inducer of transcription of this gene.
