Synonyms:IL 11 receptor subunit alpha, IL 11R alpha, IL 11R subunit alpha, IL 11RA, IL11RA, interleukin 11 receptor, alpha Background:Receptor for interleukin-11. The receptor systems for IL6, LIF, OSM, CNTF, IL11 and CT1 can utilize IL6ST for initiating signal transmission. The IL11/IL11RA/IL6ST complex may be involved in the control of proliferation and/or differentiation of skeletogenic progenitor or other mesenchymal cells. Essential for the normal development of craniofacial bones and teeth. Restricts suture fusion and tooth number.
