Notch signaling patterns Drosophila mesodermal segments by regulating the bHLH transcription factor twist

signaling targets two distinct 'Repressors of twist' -the proteins encoded by the Enhancer of split complex [E(spl)-C] and the HLH gene extra machrochaetae (emc). Hence, the patterning of Drosophila mesodermal segments relies on Notch signaling changing the activities of a network of bHLH transcriptional regulators, which, in turn, control mesodermal cell fate. Since this same cassette of Notch, Su(H) and bHLH regulators is active during vertebrate mesodermal segmentation and/or subdivision,
