Axis determination. Proteolytic generation of a morphogen

S Roth. Curr Biol. 1994.

Abstract

Ventral activation of a transmembrane receptor, Toll, is a crucial step in dorsoventral axis establishment in Drosophila embryos. The ventral ligand for Toll seems to be a proteolytic fragment of the Spätzle protein.
