分泌的刺猬(Hh)配体信号通过典型受体补丁(Ptch1)。然而,最近的研究表明,另外三种Hh结合的细胞表面蛋白Gas1、Cdo和Boc可能是Hh配体的共受体。一个核心问题是这些共受体在多大程度上起着相似的作用,以及它们在Hh信号转导中的共同需求。在这里,我们提供的证据表明,在hh介导的哺乳动物神经管腹侧神经模式中,Gas1、Cdo和Boc发挥重叠和重要的作用。具体来说,我们证明了这些分子的两个重要作用:在多个神经祖细胞的细胞命运规范中的早期作用,以及在运动神经元祖细胞维持中的后期作用。最引人注目的是,基因功能缺失实验表明,在多种组织中,Hh通路的活性都需要Gas1、Cdo和Boc。
Secreted Hedgehog (Hh) ligands signal through the canonical receptor Patched (Ptch1). However, recent studies implicate three additional Hh-binding, cell surface proteins, Gas1, Cdo and Boc, as putative co-receptors for Hh ligands. A central question is to what degree these co-receptors function similarly and their collective requirement in Hh signal transduction. Here we provide evidence that Gas1, Cdo, and Boc, play overlapping and essential roles during Hh-mediated ventral neural patterning of the mammalian neural tube. Specifically, we demonstrate two important roles for these molecules: an early role in cell fate specification of multiple neural progenitors, and a later role in motor neuron progenitor maintenance. Most strikingly, genetic loss-of-function experiments indicate an obligatory requirement for Gas1, Cdo and Boc in Hh pathway activity in multiple tissues.
