Rat IL-23R Protein (ILR-RM223) Summary
Product Description |
Recombinant Rat IL-23R Protein is expressed from HEK293 with hFc tag at the C-terminus.It contains Gly39-Asp367. |
Product Background |
Interleukin-23 (IL-23), a member of the IL-12 family of cytokines, is a heterodimeric cytokine. It is composed of subunits p40 (shared with IL-12) and p19 (an IL-12 p35-related subunit) and is secreted by several types of immune cells, such as natural killer cells and dendritic cells. The IL-23 receptor is composed of the subunit IL-12Rβ1 and the IL-23-specific subunit IL-23R. The binding of IL-23 to its specific cell surface receptor regulates a number of functions, including proliferation and differentiation of cells and secretion of cell factors. |
