ETS homologous factor isoform 2, also known as EHF, is a distinct member of the ESE subfamily of Ets transcription factors. Ets factors constitute one important class of transcriptional regulators that play critical roles in hema-topoiesis, angiogenesis, organogenesis, oncogenesis and specification of neuronal connectivity. It is exclusively expressed in a subset of epithelial cells, with highest expression detected in glandular epithelium of the prostate, pancreas, salivary gland and trachea. EHF transactivates the c-Met promoter via three high affinity binding sites, which suggests that EHF may contribute to branching morphogenesis. Recombinant human EHF protein, fused to His-tag at N-terminus, was expressed in E.coli.
