The amphioxus genome has a single Delta gene (AmphiDelta) encoding a protein 766 amino acids long. Comparison of Delta proteins of amphioxus and other animals indicates that AmphiDelta retains features of a basal bilaterian Delta protein--in having nine epidermal growth factor (EGF) repeats and also in having characteristic numbers of amino acids separating(More)
In the vertebrate central nervous system (CNS), mutual antagonism between posteriorly expressed Gbx2 and anteriorly expressed Otx2 positions the midbrain/hindbrain boundary (MHB), but does not induce MHB organizer genes such as En, Pax2/5/8 and Wnt1. In the CNS of the cephalochordate amphioxus, Otx is also expressed anteriorly, but En, Pax2/5/8 and Wnt1 are(More)
