Abstract:
The cAMP response element (CRE) and the CCAAT box of the fibronectin gene promoter are separated by only twenty base pairs. A specific factor that binds the CRE interacts cooperatively with the protein which binds to the adjacent CCAAT box, stimulating transcription [1992, J. Biol. Chem. 267, 12767-12774]. Here we show that the CRE factor is an heterodimer between a 43 kDa and the '73 kDa' CRE-binding proteins and we identify the latter as ATF-2 (also named CRE-BPI), a protein implicated in recruiting transcriptional activators to promoters, able to form heterodimers with Jun and for which a sequence-deduced MW of 55 kDa had been previously reported. © 1993.
