NCIt definition : Usually C-terminal, the conserved ETS (Erythroblast Transformation Specific) Domain
of 85-90 amino acids, rich in positively-charged and aromatic residues, binds to purine-rich
DNA with a GGAA/T core. Identified in many transcription factors, many ETS-proteins
modulate gene expression through protein-protein interactions with other transcriptional
factors and co-factors. Most ETS-proteins are nuclear targets of RAS-MAPK signaling;
some affect cell proliferation or apoptosis-related genes. Several are expressed in
specific cell lineages to regulate development and differentiation. Deregulated ETS-gene
expression or chimeric ETS-proteins are associated with leukemias, some tumors, invasion
and metastasis. (NCI);
