| Outline of Final Research Achievements |
Brorin were predominantly expressed in developing neural tissues. The loss of Brorin resulted in the activation of Bmp signaling in mice and zebrafish. brorin morphants exhibited defective development of the ventral domain in the forebrain. Furthermore, we demonstrated that Brorin inhibited Bmp signaling and played a critical role in the development of the ventral domain and specification of GABAergic interneurons and oligodendrocyte progenitors in the forebrain. It was also implicated in the suppression of astrocyte generation in the forebrain. In addition, brorin is essential for the appropriate expression of axon guidance molecules and has a role in the formation of forebrain commissural axons. The present results suggest that Brorin is a secreted Bmp antagonist predominantly expressed in developing neural tissues and that it plays multiple roles in the development of the forebrain.
