CD122\/IL-2RB is present in 3 forms with respect to ability to bind interleukin 2. The low affinity form is a monomer of the alpha subunit and is not involved in signal transduction. The intermediate affinity form consists of an alpha\/beta subunit heterodimer, while the high affinity form consists of an alpha\/beta\/gamma subunit heterotrimer. Both the intermediate and high affinity forms of CD122\/IL-2RB are involved in receptor-mediated endocytosis and transduction of mitogenic signals from interleukin 2. CD122\/IL-2RB expression was restricted to the earliest B220+ cells (CD43+CD24-; prepro B cells; fraction A) that proliferate vigorously to IL-2 in the absence of any stromal cells, but not to IL-15. The high-affinity form of this receptor is expressed on activated T lymphocytes, activated B lymphocytes, and activated macrophages. CD122\/IL-2RB plays a role in regulating normal lymphocyte development.\u003c\/p\u003e\n\n\u003cp\u003eActivity: 1.
