ERG

The ERG protein, encoded by the ETS-related gene (ERG), is a member of the ETS transcription factor family with aliases like ERG1 and ETS2-related protein. It binds to the conserved ETS DNA motif (GGAA/T core sequence) to regulate target gene transcription, governing processes such as cell proliferation, differentiation, angiogenesis, and epithelial-mesenchymal transition.
ERG intersects with VEGF, Notch, and Wnt signaling pathways, critical for vascular development and tumor progression. Abnormal ERG activity (e.g., TMPRSS2-ERG fusion in prostate cancer) links to prostate carcinoma, acute myeloid leukemia, and cardiovascular disorders. Drug研发 includes antisense oligonucleotides targeting ERG mRNA and small molecules blocking its DNA-binding ability, with preclinical studies showing potential for targeted therapy.
