Phylogenetically interrelated ETS genes, ETV1, ERM and E1A-F locate on different chromosomes.
ETV1, ERM and E1A-F are members of the multigene ETS domain containing a class of transcription factors, first identified in the genome of the avian retrovirus E26. Based upon extensive homology between these genes within their ETS domain (96% identity each other), these three genes comprise a distinct sub-family of ETS genes as a human PEA3 sub-family. By analyzing somatic cell hybrid segregating human chromosomes, the genes encoding ETV1, ERM and E1A-F were localized to human chromosome 7, 3 and 17, respectively. Fluorescence in situ hybridization confirmed these assignments and allowed mapping of the genes to 7p22 (ETV1), 3q29 ( ERM) and 17q12 (E1A-F). These results suggest the ancestral PEA3 gene may have duplicated first, then dispersed to other chromosomal locations.[1]References
