Molecular analysis and chromosome mapping of the H2A, H3 and H4 histone genes from the malaria vector Anopheles gambiae.
In this article we report the cloning and analysis of PCR generated fragments that encode H2A, H3 and H4 histone genes from the malaria vector An. gambiae. Sequence analysis indicated that some conservative changes are present in the An. gambiae H2A and H4 genes as compared with histone genes from other organisms. Divisional mapping showed that these genes map in division 20 on the left arm of the second chromosome. Southern blot experiments and the molecular characterization of the genomic fragment containing the H2A, H2B, H3 and H4 genes showed that they are organized in a cluster with an orientation different from the one found in other dipterans.
