title: Identification of promoter elements necessary for transcriptional regulation of a human histone H4 gene in vitro.
abstract: We have examined the nucleotide sequences necessary for transcription of a human histone H4 gene in vitro. Maximal transcription of the H4 promoter requires, in addition to the TATA box and cap site, promoter elements between 70 and 110 nucleotides upstream from the transcription initiation site. These distal promoter elements are recognized preferentially in extracts from synchronized S-phase HeLa cells. The inability of non-S-phase nuclear extracts to recognize the H4 upstream sequences reflects a specific lack of a transcription factor which interacts with those sequences. These results indicate that the cell cycle regulation of human histone gene expression involves both a specific transcription factor and distal transcription signals in the H4 promoter.
