Nucleotide sequence of the histone H3-encoding gene from the scleractinian coral Acropora formosa (Cnidaria: Scleractinia).

The histone H3-encoding gene from the staghorn coral Acropora formosa has the 3'-hairpin structure which functions as termination/processing signal in nonpolyadenylated histone mRNAs. The predicted amino acid sequence is highly homologous with the major H3 histones of higher metazoans, and has least homology with the corresponding protist and fungal proteins. These data are inconsistent with the phylogenetic position which has been assigned to the Cnidaria by partial 18S rRNA sequence comparison.
