Protein Description

IL-29 belongs to the type III interferon protein family, which is distinct from the type I IFNs. IL- 29 is induced by virus infection or double stranded RNA. IL-29 acts as a ligand for the heterodimeric class II cytokine receptor composed of IL10RB and IFNLR1, and receptor engagement leads to the activation of the JAK/STAT signaling pathway resulting in the expression of IFN-stimulated genes (ISG), which mediate the antiviral state.  IL-29 has antiviral, antitumour and immunomodulatory activities. IL-29 is primarily active in epithelial cells and this cell type selective action is because of the epithelial cell specific expression of its receptor IFNLR1. It also exerts an immunomodulatory effect by up regulating MHC class I antigen expression.
