The IFI16 protein also known as Interferon γ Inducible Protein 16 is a DNA sensor belonging to the PYHIN family with a molecular mass of approximately 85 kDa. Widely expressed in the nucleus and cytoplasm its primary role involves detecting foreign DNA within cells. It possesses a pyrin domain two HIN-200 domains and also plays a role in regulating gene expression particularly in response to pathogen infection. This versatile protein can act in multiple cellular environments and its location within the cell can dictate its function.
Biological function summary
IFI16 protein participates in the innate immune response by recognizing viral and bacterial double-stranded DNA. It forms part of a signaling complex that activates pathogen recognition receptors and induces the production of type I interferons. IFI16 can interact with various DNA sensors and is known for its ability to bind DNA directly providing a defense mechanism against infection. The protein also plays a role in the regulation of transcription which contributes to cell growth and differentiation.
Pathways
IFI16 protein has significant roles in the cGAS-STING and BRCA1 pathways. It interacts with cGAS to regulate the production of cyclic GMP-AMP activating STING and promoting antiviral responses. Additionally IFI16 aligns with BRCA1 dysfunction impacting DNA repair processes. This interaction underlines its involvement in maintaining genomic integrity and modulating the immune responses along with cGAS STING and BRCA1 proteins which are critical in these pathways.
IFI16 protein plays a role in autoimmune diseases and various cancers. In Systemic Lupus Erythematosus (SLE) it can induce inflammation by recognizing self-DNA leading to chronic immune activation. In certain cancers its expression levels correlate with malignancy where it influences tumor progression and response to therapy. In these contexts IFI16 interacts closely with cGAS and BRCA1 proteins highlighting its relevance to disease mechanisms and offering potential therapeutic targets.
