bullwinkle and shark regulate dorsal-appendage morphogenesis in Drosophila oogenesis.

Development (Cambridge, England) - 1 Dec 2003

Tran David H, Berg Celeste A

Abstract excerpt

bullwinkle (bwk) regulates embryonic anteroposterior patterning and, through a novel germline-to-soma signal, morphogenesis of the eggshell dorsal appendages. We screened for dominant modifiers of the bullwinkle mooseantler eggshell phenotype and identified shark, which encodes an SH2-domain, ankyrin-repeat tyrosine kinase. At the onset of dorsal-appendage formation, shark is expressed in a punctate pattern in...
