High impact information on esr9

  • Here, we show that the Xenopus Hairy-related transcription factor (HRT) gene XHRT1, and the Hairy/Enhancer of split (HES) genes Xhairy1, Xhairy2b, esr9 and esr10, have distinct restricted dynamic expression patterns during pronephros development, and that their expression is regulated by Notch [1].
  • Here, we describe the expression of Xenopus esr9 and esr10, two new members of the Hairy/Enhancer of split related family of bHLH proteins [2].
  • Cyclic expression of esr9 gene in Xenopus presomitic mesoderm [2].
