IRF-3 is a roughly 50 kD member of the interferon regulatory transcription factor (IRF) family. Along with other members of the IRF family IRF-3 plays a key role in the innate immune response to viral infection. It is located ubiquitously in an inactivated form in the cytoplasm of many immune cells. When phosphorylated it forms a complex with CREBBP to upregulate many immune responses integral to innate immune function.

- Recommended Usage
-
Each lot of this antibody is quality control tested by intracellular immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is 5 µL per million cells in 100 µL staining volume or 5 µL per 100 µL of whole blood. It is recommended that the reagent be titrated for optimal performance for each application.

Antigen Details
- Structure
- Human IRF-3 has 427 amino acids with predicted Mw 47.2 kD and observed Mw 52 kD. Contains an IRF tryptophan pentad repeat responsible for DNA binding. Mouse Irf-3 has 419 amino acids with predicted MW 46.9 kD and observed Mw 45 kD.
- Distribution
-
Inactive IRF-3 continuously transits between the cytoplasm and nucleus. Serine/threonine phosphorylation or IRF-3 results in the structural changes which allow IRF-3 activation. The activated IRF3 translocates to the nucleus, where it forms a complex with CREB binding protein and activates the transcription of interferons, interferon stimulated genes, and other antiviral response genes.
- Function
- CREB binding protein, IRF-7, TICAM-1, TICAM-2, non-canonical IKB kinases TBK1 and IKKε.
