Interleukin-9 is a protein that acts as one of the regulators of hematopoiesis. IL-9 is an enhancer of cells and megakaryoblastic leukemic cells’ growth. Among this protein’s producers we can find cells like mast cells, Treg, NKT cells, Th17, Th2, ILC2, and Th9 cells in various amounts. Th9 are the primary CD4 cells (T cells) that IL-9 is produced in.
IL-9 Human produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 132 amino acids (19-144 aa) and having a molecular mass of 14.9kDa.IL-9 is fused to a 6 amino acid His tag at C-terminus and purified by proprietary chromatographic techniques.
| UniProt Protein Function: | IL9: Supports IL-2 independent and IL-4 independent growth of helper T-cells. Belongs to the IL-7/IL-9 family. |

| NCBI Summary: | The protein encoded by this gene is a cytokine that acts as a regulator of a variety of hematopoietic cells. This cytokine stimulates cell proliferation and prevents apoptosis. It functions through the interleukin 9 receptor (IL9R), which activates different signal transducer and activator (STAT) proteins and thus connects this cytokine to various biological processes. The gene encoding this cytokine has been identified as a candidate gene for asthma. Genetic studies on a mouse model of asthma demonstrated that this cytokine is a determining factor in the pathogenesis of bronchial hyperresponsiveness. [provided by RefSeq, Jul 2008] |
