Official Full Name
IL2RB interleukin 2 receptor, beta
BackgroundCD122 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 (gammac, CD132) alone or with the gammac 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.
