... multicomponent receptors consisting of the Ret receptor tyrosine kinase plus one of two structurally related GPI- linked receptors, GFRα-1 and GFRα-2. To ascertain how the expression of these receptors is regulated during development, we cultured embryonic neurons under different experimental conditions and used...

...Rachel Gollop; Alan R. Kimmel ABSTRACT To understand how positional information within an organism specifies patterning during development, we are analyzing spatially regulated gene expression in Dictyostelium . CAR3 is a member of the cAMP, 7-span receptor family which directs the transition from...

...Kevin Fitzgerald; Hilary A. Wilkinson; Iva Greenwald ABSTRACT Members of the lin-12/Notch gene family encode receptors for intercellular signals and are found throughout the animal kingdom. In many animals, the presence of at least two lin-12/Notch genes raises the issue of the significance...
