【 摘 要 】

Replacement variant genes for different histones have been described in most higher eukaryotes. However, so far no such gene has been found for histone H4. We have isolated from both Drosophila melanogaster and D. hydei a novel histone H4 encoding gene, H4r, which displays all the properties of a histone replacement variant gene: it contains introns, generates polyadenylated mRNA, represents the predominant H4 transcript in non-dividing tissues and is present in the genome as a single copy. The encoded polypeptide is identical to the Drosophila cell-cycle regulated histone H4. The fact that it is a single copy gene makes it prone to genetic analysis and it might be a useful tool for studying nucleosome structure and function.
