摘要: The promoter-specific factor E2F interacts with critical regulatory sequences within the adenovirus E2 promoter. In addition, level of active increases markedly during a virus infection, dependent on E1A function and coincident trans activation transcription. We have purified through combination standard biochemical procedures DNA affinity chromatography. was single polypeptide 54,000 molecular weight, as determined by UV crosslinking renaturation gel-fractionated protein. Addition affinity-purified to an in vitro transcription system resulted stimulation from promoter containing two E2F-binding sites but not promoters lacking binding sites. thus conclude that is indeed capable stimulating once it has bound
