Nuclear proteins translationally repressed by v-Abl included transcription factors implicated in repressing the IgH locus (Ezh2 (NM_007971), Cux1/Cutl1 (NM_009986), Bach2 (NM_007521), perhaps with MafG (NM_010756)) [43], [44], [45], [46], [47], activating RAG and/or promoting B cell differentiation (Foxp1 (NM_053202), Lef1 (NM_010703), Bcl6 (NM_009744)) [48], [49], [50], [51], and tumor suppression (Ssbp2 (NM_024186), Mll5 (NM_026984)) [52], [53]. The gene discussed is LEF1; the disease is neoplasm.
