Avian leukemia virus E26 is a replication defective retrovirus that induces a mixed erythroid/myeloid leukemia in chickens. E26 virus carries two distinct oncogenes, v-myb and v-ets. The ets portion of this oncogene is required for the induction of erythroblastosis. V-ets and c-ets-1, its cellular progenitor, have been shown  to be nuclear DNA-binding proteins. Ets-1 differs slightly from v-ets at its carboxy-terminal region. In most species where it has been sequenced, c-ets-1 exists in various isoforms generated by alternative splicing and differential phosphorylation.
A number of proteins, that share regions of similarity with v-ets/c-ets-1, have been found and are listed below:
All these proteins contain a conserved domain, the 'ETS-domain', [2,3,4,5] involved in DNA-binding. It seems to recognize purine-rich sequences . This domain, of about 85 to 90 amino acids, is rich in aromatic and positively charged residues. It is generally localized at the C-terminus of the protein, with the exception of ELF-1, ELK-1, ELK-3, ELK-4 and ERF where it is found at the N-terminus.
We have derived two signature patterns for the ETS-domain. The first one is based on a highly conserved region in the N-terminal part of the domain, while the second is based on a region in the second third of the domain. The profile spans the complete domain.Last update:
