ATOH1 is a transcriptional regulator that activates E-box-dependent transcription in collaboration with TCF3/E47. Its activity is completely antagonized by HES1, a negative regulator of neurogenesis. ATOH1 plays a role in the differentiation of specific neural cell subsets by activating E-box-dependent transcription.
