The IL-2Rβ/CD122 (Ab-364) antibody targets the interleukin-2 receptor beta subunit (IL-2Rβ), a key component of the high-affinity IL-2 receptor complex. IL-2Rβ, encoded by the *IL2RB* gene, is a type I transmembrane protein that pairs with the common gamma chain (γc, CD132) to form the functional receptor for IL-2 and IL-15 cytokines. This receptor subunit is critical for signal transduction in activated T cells, natural killer (NK) cells, and regulatory T cells (Tregs), influencing immune cell proliferation, survival, and differentiation. The cytoplasmic domain of IL-2Rβ interacts with JAK1 kinase, initiating downstream pathways like STAT5 activation, which regulates gene expression linked to immune responses.
Clone 364 is a monoclonal antibody commonly used in research to detect CD122 in applications such as Western blotting, immunohistochemistry, and flow cytometry. It recognizes an epitope within the intracellular domain, enabling specific identification of endogenous CD122 expression. Dysregulation of IL-2Rβ signaling is associated with autoimmune diseases, immunodeficiency, and cancer, making this antibody a valuable tool for studying T cell exhaustion, checkpoint inhibitor responses, and cytokine-driven therapies. Its role in IL-15 signaling also links it to NK cell-mediated immunity, highlighting its relevance in immunotherapy and immune microenvironment studies.
