The EVI1 gene is activated by chromosomal translocations and inversions in approximately 5% of human acute myeloid leukemia (AML) and by retroviral insertion in approximately 20% of murine myeloid leukemias. EVI1 encodes a nuclear DNA-binding protein having 10 zinc finger motifs in two noncontiguous domains consisting of an amino-terminal domain of seven fingers and a carboxyl domain containing three fingers. To evaluate the sequence specificity of Evi-1 binding and potentially identify genomic targets, whole-genome PCR was utilized to isolate multiple Sau3A fragments which specifically bind to the amino-terminal zinc finger domain. The majority of these clones represented single copy sequences and virtually all contained variable numbers of repeats of the GATA motif, the target sequence for the erythroid-specific transcription factor GATA-1. GST/Evi-1 fusion proteins containing the amino-terminal domain of zinc fingers bound the GATA motif in these clones as well as to those present in the human gamma-globin promoter, similar to the binding of purified GATA-1 protein. By obtaining corresponding large genomic clones for eight of these fragments, transcription units were found associated with two. One corresponded to the glyceraldehyde-3-phosphate dehydrogenase gene and its expression was not affected by Evi-1. The second is a novel gene whose expression is repressed in murine myeloid cell lines that express Evi-1.
