Additional levels of complexity of Evi1 function relevant to OM pathogenesis may result from the first (N-terminal) zinc-finger domain binding to a number of putative target genes Gadd45g, Gata2, Zfpm2/Fog2, Skil (SnoN), Klf5 (BTEB2), Dcn, and Map3k14 (Nik) [35]. This evidence concerns the gene DCN and ocular melanoma.
