Genome-wide analysis of Sox genes in Drosophila melanogaster

Abstract

Genes of the Sox family encode evolutionarily conserved HMG box containing transcription factors, which play key roles in various events of cell determination/differentiation during development. The total number of Sox genes in Drosophila melanogaster was estimated to be eight, after classical molecular cloning approaches and exhaustive screening of the complete Drosophila genome. Here we report the embryonic and larval expression pattern of four previously uncharacterized Sox genes, through antibody staining and in situ hybridization experiments.
