Background
Interleukin-10
Receptor alpha (IL-10 R alpha), also known as IL-10 R1, is a 51 kDa transmembrane
glycoprotein member of the class II cytokine receptor family (1). IL-10 R alpha
is required for mediating the effects of IL-10, a critical molecule in the
control of microbial infections, allergic and autoimmune inflammation, and
cancer (2-5). IL-10 R alpha is the ligand specific subunit of the IL-10
receptor complex. Noncovalent dimers of IL-10 bind to IL-10 R alpha, resulting in the recruitment of IL-10 R beta (6-8). IL-10 R
beta is a ubiquitously expressed transmembrane protein that does not bind IL-10
by itself but is required for signal transduction and in vivo IL-10
responsiveness (7, 9). IL-10 R beta also associates with IL-20 R alpha, IL-22 R
alpha, or IL-28 R alpha to form the receptor complexes for IL-22, IL‑26, IL-28,
and IL-29 (1). Polymorphisms of human IL-10 R alpha may limit viral immune
evasion by retaining full responsiveness to human IL-10 but responding weakly
to the cytomegalovirus homolog of IL-10 (11). Mature IL-10 R alpha consists of
a extracellular domain (ECD), a transmembrane segment, and a cytoplasmic domain
(12). Within the ECD, cynomolgus monkey IL-10 R alpha shares 95%, 59% and 60%
amino acid identity with Human, mouse, and rat IL-10 R alpha, respectively.
