Irf7 phosphorylation

Websignaling pathways downstream of PRRs lead tothe phosphorylation of IFN regulatory factor 7 (IRF7) and IRF3, thus promoting their di-merization and translocation to the nucleus where they activate the transcription of type I IFN genes. IRF3 and IRF7 share some structural and functional similarities, WebNov 7, 2016 · Phosphorylation of IRF7 is necessary for IFN- α signal transduction, followed by nuclear translocation and activation of type I IFN gene transcription [ 7, 8 ]. However, when the expression of type I IFN is dysregulated, adverse immunological effects may result.
