Identification of the rabies virus alpha/beta interferon antagonist: phosphoprotein P interferes with phosphorylation of interferon regulatory factor 3.
Rabies virus (RV) of the Rhabdoviridae family grows in alpha/beta interferon (IFN)-competent cells, suggesting the existence of viral mechanisms preventing IFN gene expression. We here identify the viral phosphoprotein P as the responsible IFN antagonist. The critical involvement of P was first suggested by the observation that an RV expressing an enhanced green fluorescent protein (eGFP)-P fus...
متن کاملActivation of Interferon Regulatory Factor 5 by Site Specific Phosphorylation
The cellular defense to infection depends on accurate activation of transcription factors and expression of select innate immunity genes. Interferon regulatory factor 5 (IRF5), a risk factor for systemic lupus erythematosus, is activated in response to pathogen recognition receptor engagement and downstream effector molecules. We find the nucleotide-binding oligomerization domain containing pro...
متن کاملIdentification of the minimal phosphoacceptor site required for in vivo activation of interferon regulatory factor 3 in response to virus and double-stranded RNA.
The ubiquitously expressed latent interferon regulatory factor (IRF) 3 transcription factor is activated in response to virus infection by phosphorylation events that target a cluster of Ser/Thr residues, (382)GGASSLENTVDLHISNSHPLSLTSDQY(408) at the C-terminal end of the protein. To delineate the minimal phosphoacceptor sites required for IRF-3 activation, several point mutations were generated...
متن کاملIdentification of a Phosphorylation-Dependent Nuclear Localization Motif in Interferon Regulatory Factor 2 Binding Protein 2
BACKGROUND Interferon regulatory factor 2 binding protein 2 (IRF2BP2) is a muscle-enriched transcription factor required to activate vascular endothelial growth factor-A (VEGFA) expression in muscle. IRF2BP2 is found in the nucleus of cardiac and skeletal muscle cells. During the process of skeletal muscle differentiation, some IRF2BP2 becomes relocated to the cytoplasm, although the functional...
متن کاملIdentification of a critical regulatory site in the human interleukin-3 promoter by in vivo footprinting.
Interleukin-3 (IL-3) is involved in proliferation and differentiation of hematopoietic progenitor cells. Its expression is subject to precise, tissue-specific regulation, and has been studied extensively in the gibbon T-cell line MLA 144 by a combination of functional assays and DNA binding experiments. To extend these studies, the gibbon IL-3 promoter was cloned and in vivo footprinting of the...
