    ..cells expressing btd generate their own signalling system, including the establishment of a sharp boundary of engrailed expression, and the local activation of the wingless and decapentaplegic genes...

    ..However, if cell death is prevented, JNK activation can trigger tissue overgrowth. Thus, MKPs are key regulators of the delicate balance between proliferation, differentiation and apoptosis during development. ..

    ..We propose that the association of the Cos2 protein complex with Smo at the plasma membrane controls the stability of the complex and allows Ci activation, eliciting its nuclear translocation. ..
