In the field of molecular biology, the ETS (E26 transformation-specific[2] or E-twenty-six. (Erythroblast Transformation Specific)[3]) family is one of the largest families of transcription factors and is unique to animals. There are 28 genes in humans[4], 27 in the mouse, 10 in Caenorhabditis elegans and 9 in Drosophila. The founding member of this family was identified as a gene transduced by the leukemia virus, E26. The members of the family have been implicated in the development of different tissues as well as cancer progression.
