IL-11R alpha

IL-11R alpha (IL-11RA) is the IL-11 receptor subunit α and also acts as an agonist of IL-11. IL-11R alpha binds to IL6ST/gp130 on cell surfaces and induces signal transduction[1]. IL-11R alpha activates Jak family of tyrosine kinases, JAK1, JAK2, and TYK2[2]. IL-11R alpha induces proliferation and/or differentiation of skeletogenic progenitor or other mesenchymal cells[3]. IL-11R alpha plays an important role in the progression and the differentiation of human gastric carcinomas[4].
