Description:This 9A2-CD122 monoclonal antibody reacts with human CD122, which is also known as interleukin-2 receptor beta (IL-2R beta). This receptor is expressed on NK cells, activated T cells, some B cells, monocytes, and T cell leukemias. CD122 can also be detected during early NK cell commitment. IL-2R beta associates with the IL-2R alpha (CD25) or IL-15R alpha and common gamma chain (CD132) to form the high affinity IL-2 and IL-15 receptors, respectively. By itself, this membrane receptor can bind IL-2, but with intermediate affinity. The binding of IL-2 results in internalization of the cytokine, tyrosine phosphorylation of IL-2Rβ, and activation of signaling cascades such as the JAK/STAT pathway.
