Abstract

Definition of mechanisms regulating human histone H1 gene transcription during the cell cycle requires the isolation and biochemical characterization of protein factors which interact with specific promoter elements. Two distinct binding activities have been identified in nuclear extracts from HeLa cells and mapped within a 180-base-pair (bp) region of a cell cycle-regulated H1 gene promoter. H1TF1 bound to an H1-specific A + C-rich sequence (AC box), 100 bp upstream of the cap site; H1TF2 interacted with the H1 subtype-specific consensus element and was dependent on the presence of an intact CCAAT box for binding. H1TF2 was purified through a combination of ion-exchange and oligonucleotide affinity chromatographies. Analysis of purified fractions by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and UV crosslinking showed that H1TF2 was a single polypeptide of 47 kilodaltons. This factor was distinct from previously characterized CCAAT-binding proteins in both molecular size and binding properties. Fractions containing H1TF2 activity activated transcription in vitro only if programmed with an H1 DNA template carrying an intact H1TF2-binding site.
