Phylogenetically interrelated ETS genes, ETV1, ERM and E1A-F locate on different chromosomes

Abstract:
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.

Chromosome Structure
The centromere is a DNA sequence that links sister chromatids. This is also where kinetochores, protein complexes to which spindle microtubules attach, are constructed after the chromosome is replicated. The kinetochores allow the spindle microtubules to move the chromosomes within the cell during cell division.
