Drosopholia eye development is an example of cell differentiation directed by signal binding to a receptor tyrosine kinase (RTK). In this pathway, R7 photoreceptor development requires a receptor (SEV, sevenless), which is activated by binding to a plasma membrane bound signal (BOSS, bride-of-sevenless) displayed on the adjacent R8 cell Receptor activation leads to activation of RAS via two proteins, Drk (down- stream of receptor kinases) and Sos (son-of-sevenless). Activated RAS leads to activation of a phosphorylation cascade that activates the...
