背景（Background）
Interferon alpha/beta receptor 2 (IFR2) is also known as IFN-alpha binding protein, IFN-alpha/beta receptor 2, Type I interferon receptor 2, IFBR and IFRB, which is a single-pass type I membrane protein and belongs to the type II cytokine receptor family. IFR2 can associate with IFR1 to form the type I interferon receptor. IFR2 is a receptor for interferons alpha and beta.IFR2 involves in IFN-mediated STAT1, STAT2 and STAT3 activation. Isoform 1 and isoform 2 of IFR2 are directly involved in signal transduction due to their association with the TYR kinase, JAK1. Isoform 3 of IFR2 is a potent inhibitor of type I IFN receptor activity.Genetic variations in IFR2 influence susceptibility to hepatitis B virus (HBV) infection.
