The CAAT box is what is known as a core promoter, also known as the basal promoter or simply the promoter, is a region of DNA that initiates transcription of a particular gene. This region, in particular for the CAAT box, is located about 60–100 bases upstream (towards the 5' end), however no less than 27 base pairs away, from the initial transcription site or a eukaryote gene in which a complex of general transcription factors bind with RNA polymerase II prior to the initiatio… WebCellular Component Description A heteromeric transcription factor complex that binds to the CCAAT-box upstream of promoters; functions as both an activator and a repressor, depending on its interacting cofactors.
