Abstract
The expression of one of the human main type H1 histone genes (termed H1.2) appears to be regulated by several trans-acting factors. Upstream of consensus regulatory regions, such as the TATA-, CCAAT- and H1-box (AAACACA) sequences, a crucial control site is located between nucleotide positions -536 and -412 (relative to the ATG initiation site). Removal of this promoter portion causes in chloramphenicol acetyl transferase reporter gene constructs a loss of the S-phase control function of the H1.2 promoter in HeLa cells. Electrophoretic mobility-shift assay and DNase I footprinting analysis suggest that the H1-box variant AAACAGA is a potential control element within the distal promoter region.Keywords
