Clone TM-β1 recognizes an epitope on mouse CD122.

CD122 is a 70-75 kD IL-2 receptor β chain that is a type I membrane protein. CD122 is involved in T cell-mediated immune responses and its activation increases proliferation of CD8+ effector T cells. It exists in three forms with varying degrees of binding affinity with IL-2. The low affinity form is a monomer of the α subunit and has no involvement in signal transduction. The intermediate affinity form is a γ/β heterodimer and the high affinity form is an α/β/γ heterotrimer. The intermediate and high affinity forms of the receptor are involved in receptor-mediated endocytosis and transduction of mitogenic signals from interleukin 2. This protein also interacts with the IL-15 receptor.

CD122 is expressed on NK cells and at lower levels by T lymphocytes, B lymphocytes, monocytes, and macrophages.
