Abstract:
Previously we have shown that the 3' untranslated regions (UTRs) of the replacement histone genes H3.3.A and H3.3B of Drosophila melanogaster differ in their nucleotide sequences and have different polyadenylation sites. To understand their functional relevance, which might explain the presence and evolutionary conservation of 2 different H3.3 genes, green fluorescent protein (GFP) constructs with different 3' UTR sections were studied by the expression of GFP as a marker protein. Here we show that the polyadenylation signals modify the cell-specific translation of the histone replacement variants in testes and ovaries. The H3.3A gene may be required to provide postmeiotic histone H3.3 in the male germ line in transition to chromatin packaging in sperm.
