This entry represents the Fibronectin type III (FN3) domain found at the N-terminal of Interleukin-27 subunit beta (IL27B), from animals. This domain may be found in association with a C-terminal FN3 (Pfam:PF00041). Also known as EBI3, IL27B binds p28 to form the heterodimeric cytokine IL-27, which plays an important role in innate immunity by inducing naive CD4+ T cells proliferation [1]. IL-27 binds GP130 and IL-27Ra, acting as a bridge, to activate the JAK/STAT signaling cascade. EBI3 stabilizes the complex by binding a positively charged surface of IL-27Ra and Domain 1 of GP130 [2].	Domain
