Description
Interleukin-2
receptor subunit beta (IL-2 RB), also known as high affinity IL-2 receptor
subunit beta, interleukin-15 receptor subunit beta, p70-75 (p75), and CD122, is
a member of the cytokine receptor superfamily that plays a role in T
cell-mediated immune responses (1, 2). Human IL-2 RB consists of an
extracellular domain (ECD) containing a fibronectin type III domain and a WSXWS
motif, a type I transmembrane domain, and a cytoplasmic tail. The gamma chain
of the high affinity functional human IL-2 receptor complex belongs to the
hematopoietin receptor family. IL-2 R gamma is a 369 amino acid residue protein
consisting of a 22 residue signal sequence, a 232 residue extracellular domain,
a 29 residue transmembrane domain and an 86 residue cytoplasmic domain. Functional
IL-2 receptors can exist in two affinity states on cell surfaces: the high
affinity complex consisting of heterotrimers of the alpha, beta, and gamma
chains and the intermediate affinity complex comprising heterodimers of the
beta and gamma chains (2, 3). Individual beta chains and alpha chains exhibit
low affinity IL-2 binding and the gamma chain alone does not bind IL-2. In
addition to their involvement in IL-2 mediated signal transduction, both the
beta chain and gamma chain have been shown to be required for IL-15 mediated
signaling (4).
