Clone Host Grade Applications
Monoclonal Rabbit Supernatant B IC
A family of interferon (IFN) regulatory factors (IRFs) have been shown to play a role in transcription of IFN genes as well as IFN-stimulated genes. The IRF-3 gene encodes a 50-kD protein that binds specifically to the IFN- stimulated response element (ISRE) (1).IRF-3 is activated through phosphorylation by the kinases IKK epsilon and/or TBK1.Phosphorylation results in IRF-3 dimerization and removal of an autoinhibitory structure to allow interaction with the coactivators CBP/p300. Phosphorylation at Serine 396 through Serine 405 alleviates autoinhibition to allow interaction with CREB-binding protein and facilitates phosphorylation at Serine 385 or Serine 386 (2).Serine 386 is suggested to be the target of the IRF-3 kinase and critical determinant for the activation of IRF-3 (3).
