The functional organization of the rat brain creatine kinase (ckb) promoter was analyzed by deletion, linker scanning, and substitution mutagenesis. Mutations were introduced into the ckb promoter of hybrid ckb/neo (neomycin resistance gene) genes, and the mutant genes were expressed transiently in HeLa cells. Expression was assayed by primer extension analysis of neo RNA, which allowed the transcription start sites and the amount of transcription to be determined. Transfections and primer extension reactions were internally controlled by simultaneous analysis of transcription from the adenovirus VA gene located on the same plasmid as the hybrid ckb/neo gene. We demonstrate that 195 bp of the ckb promoter is sufficient for efficient in vivo expression in HeLa cells. A nonconsensus TTAA element at -28 bp appears to provide the TATA box function for the ckb promoter in vivo. Two CCAAT elements, one at -84 bp and the other at -54 bp, and a TATAAA TA element (a consensus TATA box sequence) at -66 bp are required for efficient transcription from the TTAA element. In addition, we present evidence that the consensus beta-globin TATA box responds to the TATAAATA element in the same way as the ckb nonconsensus TTAA element.
