Ccaat-binding factor
WebQuestion: Specificity protein 1 (Spl) and CCAAT-binding transcription factor 1 (CTF1) are DNA-binding transcription factors in eukaryotes. Spl binds to the GC box sequence, whereas CTF1 binds to the CCAAT site. Suppose the DNA-binding domains of these two transcription factors have been successfully swapped with each other. WebWe report the isolation of a novel cDNA clone encoding a 114-kDa polypeptide that binds to the CCAAT element of the hsp70 promoter. Expression of this CCAAT-binding factor …
