Homo sapiens interferon regulatory factor 3 (IRF3), transcript variant 1
Synonyms:
MGC94729; interferon regulatory factor 3
Immunogen
A phospho-specific peptide corresponding to residues surrounding Serine 386 of human IRF3 was used as an immunogen. The antibody only detects IRF3 phosphorylated on Serine 386.
Buffer
50 mM Tris-Glycine (pH 7.4), 0.15 M NaCl, 40% Glycerol, 0.01% sodium azide and 0.05% BSA.
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-kDa 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).
