Interferon regulatory factor 8

Gene

Irf8

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Plays a role as a transcriptional activator or repressor (By similarity). Specifically binds to the upstream regulatory region of type I IFN and IFN-inducible MHC class I genes (the interferon consensus sequence (ICS)). Plays a negative regulatory role in cells of the immune system. Involved in CD8+ dendritic cell differentiation by forming a complex with the BATF-JUNB heterodimer in immune cells, leading to recognition of AICE sequence (5'-TGAnTCA/GAAA-3'), an immune-specific regulatory element, followed by cooperative binding of BATF and IRF8 and activation of genes (PubMed:22992524). Positively regulates macroautophagy in dendritic cells (By similarity).By similarity1 Publication

Post-translational modificationi

Ubiquitinated (PubMed:17579016). Ubiquitination by TRIM21 in macrophages, a process that is strongly increased upon interferon gamma stimulation, leds to the enhanced transcriptional activity of target cytokine genes (PubMed:17579016). Ubiquitination leads to its degradation by the proteasome (By similarity).By similarity1 Publication
