Interleukin 2 Receptor Antibody: Anti-Mouse CD122/IL-2R beta Rat MoAb

The Interleukin 2 receptor (also known as IL-2R) is involved in signaling that affects T cell proliferation, and is comprised of three subunits: alpha, beta, and gamma. This monoclonal antibody (clone TM-beta 1) is an IL-2 receptor antibody. It binds to the IL-2 receptor beta subunit  and may be used for in vitro neutralization assays, as well as inhibiting the association between IL-2 and IL-2R beta subunit in vivo.

Although the IL-2R alpha and beta subunits can each bind IL-2 as monomers, the heterodimer complex formed through association of IL-2R alpha and beta subunits has a faster association rate and a slower dissociation rate for IL-2  versus either subunit by itself. Once the IL-2R alpha-beta dimer forms and binds IL-2, the gamma subunit is recruited. Activation of the JAK/STAT pathway, the MAP kinase pathway, and the PI3K pathway may then occur. IL-2 receptor beta is a type I membrane protein that binds IL-2 and associates with JAK1. IL-2R beta is also known as CD122, IL15RB, P75, and P70-75.
