Interleukin-2 Receptor Beta Gamma Complex (IL-2Rβγ)

Target
IL-2Rβγ
Molecular classification
Receptor, Cytokine receptor complex, Type I cytokine receptor
01

Overview

The interleukin-2 receptor (IL-2R) beta gamma complex refers to the combination of the IL-2 receptor beta (IL-2Rβ, CD122) and common gamma chain (γc, CD132), which together form an intermediate-affinity binding site for interleukin-2 (IL-2). It is crucial for signal transduction, lymphocyte proliferation, and immune homeostasis. Defects can lead to immunodeficiency, while therapeutic targeting is explored for cancer immunotherapy and autoimmune diseases.
