IRF3 also known as Interferon Regulatory Factor 3 acts as an important transcription factor in the immune response. It has a molecular weight of approximately 47 kDa. The IRF3 protein is mainly expressed in the cytoplasm and nucleus of various cell types including immune cells such as macrophages and dendritic cells. The protein becomes activated through phosphorylation a process frequently identified in its phosphorylated form phospo-IRF3 or p-IRF3 which facilitates its role in immune function.
Biological function summary
IRF3 participates in the regulation of type I interferon (IFN) response a fundamental antiviral defense mechanism. IRF3 when phosphorylated forms a complex with CBP/p300 which then translocates to the nucleus to drive the expression of IFN-stimulated genes. This action strengthens the innate immune response and boosts the body's ability to counteract viral infections. Its activity and regulation are significant for maintaining a balanced immune response without excessive inflammation.
Pathways
IRF3 is involved in the Toll-like receptor (TLR) and RIG-I-like receptor (RLR) signaling pathways both essential in pathogen recognition and response. Within these pathways IRF3 interacts with proteins such as MAVS and TBK1 to propagate immune signaling. The activation of IRF3 in these pathways results in the production of type I interferons and other cytokines orchestrating an effective antiviral response. These interactions highlight the protein's central role in mediating immune signaling cascades.
IRF3's malfunction or deregulation can contribute to autoimmune diseases and antiviral deficiencies. Conditions such as systemic lupus erythematosus (SLE) and chronic hepatitis B infection are linked to IRF3 activity. During autoimmune responses or viral persistence the aberrant activation of IRF3 can lead to inappropriate immune responses. The connection with proteins like STAT1 in these conditions highlights the complex network IRF3 engages in facilitating its impact on disease progression and immune dysregulation.
