Molecular model of a complex formed between Spi-1/Pu.1 and IRF8 transcription factor proteins bound to DNA. The formation of this sort of structure was recently reported by the Auron laboratory to be a likely component for expression of the interleukin 1beta (IL1B) gene in response to bacterial infection.
