Hoxa-4
Foreign sequence; species == Mus musculus; gene == Hoxa4; MGI:96176.
The intron of Mmus\Hoxa4 contains an enhancer that is regulated by a number of homeobox genes in transgenic Drosophila. The enhancer is directly activated by Ubx, and is repressed by abd-A.
The intron of Mmus\Hoxa4 contains an enhancer that is selectively activated by posterior homeotic genes in Drosophila imaginal discs in third instar, wandering stage larvae.
