The CD25 antigen (IL-2Rα chain, Tac or p55) is a single-chain glycoprotein with a molecular weight of 55 kDa which is the low affinity receptor for IL-2 (IL-2Rα). In conjunction with CD122 (IL-2Rβ, p75) and CD132 (IL-2Rγ, p64), CD25 antigen forms the high-affinity IL-2R complex. CD25 antigen is found on activated T and B cells, on activated monocytes and macrophages, and on T cell clones. It is also expressed on NK cells enriched from peripheral blood lymphocytes by culturing in the presence of IL-2. It is absent from thymocytes and resting T and B lymphocytes.
