IFN-gamma receptor

The IFN-γR is a heterotetramer comprised of two α-chains (R1) and two β- chains (R2) that are constitutively associated with Jak1 and Jak2, respectively. Upon ligand binding to IFN-γR1, activation of Jak1 and Jak2 ensues leading to phosphorylation of tyrosine on IFN-γR1, thereby generating a docking site for the transcription factor Stat1α. Once at the activated receptor complex, Stat1α monomers homodimerize and are phosphorylated on tyrosine. The phosphorylated homodimer disassociates from the receptor and translocates to the nucleus where it binds to IFN-γ activated sequences (GAS) elements in IFN-γ-regulated genes.
