title: Atonal points the way- protein-protein interactions and developmental biology.
abstract: Many cells maintain their state of determination long after the signals that induced it decay. In this issue of Developmental Cell, zur Lage and colleagues describe how certain cells sustain proneural gene expression through direct interactions between transcription factors.
