General Information
The Ets family of transcription factors is known to control the expression of genes critical for cellular proliferation, differentiation, and transformation. They activate transcription by interaction with purine-rich sequences in promoter/enhancer regions of various genes. Differential expression of Ets genes is particularly associated with embryonic development of the central nervous system. Previous studies have implicated Ets transcription factors in apoptosis; however, exact mechanisms remain unclear. The mammalian Ets1 gene encodes a set of nuclear phosphoproteins ranging in size from 42 to 54kD.
