CD122 is a 70-75 kD IL-2 receptor beta chain also known as IL-2Rbeta, which is also shared by the IL-15 receptor. It is constitutively expressed by NK cells and at lower levels by T cells, B cells, monocytes, and macrophages. The IL-2Rbeta chain can combine with either the common gamma subunit (gamma-c, CD132) alone or with the gamma-c subunit and the IL-2Ralpha subunit (CD25) to generate intermediate or high affinity IL-2 receptor complexes, respectively. CD122 expression levels can be upregulated by activation. The 5H4 antibody does not block IL-2 binding to the IL-2 receptor. CD122 is expressed on murine, but not human, CD8+ Tregs involved in the maintenance of T cell homeostasis.
