Popis: Ph+ and Ph-like B-ALL remain poor prognosis leukemias. VAV3, a guanine nucleotide exchange factor, is activated and overexpressed in these leukemias. Here the authors reveal that leukemic VAV3 is predominantly nuclear. Nuclear VAV3, through its guanine nucleotide exchange factor and its effector nuclear RAC2, controls the repressive transcriptional activity of the polycomb repression complex-1 via nuclear AKT/PHLPP2 regulated BMI1.
