The intracellular domain of NOTCH2 (Notch2IC) interacts with the repression domain of CBF1 (RBPJ), translocates to the nucleus, transactivates CBF1-responsive target genes by masking CBF1-mediated repression, activates endogenous HES-1, and blocks muscle cell differentiation — the same mechanism used by NOTCH1 and mimicked by EBV EBNA2. |
