More Information
Clone 5H4
Isotype Rat (Lewis) IgG2aκ
Isotype Control Rat IgG2a-LE/AF (KLH/G2a-1-1)
Specificity Mouse CD122
Alternative Names IL-2Rβ, IL-15 receptor β chain
Description The IL-2 receptor is a complex of three distinct polypeptide chains: (i) the α chain which binds IL-2 with low affinity; (ii) the β chain that binds IL-2 with high affinity; and (iii) the common γ chain (γc) that does not bind IL-2. The high affinity receptor complex is an α/β/γ heterotrimer with a Kd of 1.3 x 10-11 M. In mouse spleen, CD122 is expresed on ~30% of CD8+ cells and all NK cells but <1% of B cells and CD4+ T lymphocytes. In the thymus, its expression is confined to CD4-CD8+ single positive and CD4-CD8- double negative cells. Cytoplasmic regions of the IL-2R β chain are involved in IL-2-mediated cellular signaling and, via the interaction of IL-2 and its receptor complex, may be involved in the generation and differentiation of T lymphocytes. The monoclonal antibody 5H4 does not block IL-2 binding.
