...David H. Tran; Celeste A. Berg 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...

... Bullwinkle Ras/Raf pathway Transcriptional repression Vein development Drosophila Activation of receptor tyrosine kinases (RTKs) by secreted growth factors regulates cell proliferation and cell fate determination in many different cellular and developmental contexts. Despite such widespread...

...Kimberley R. Rittenhous; Celeste A. Berg ABSTRACT Subcellular localization of gene products and cell migration are both critical for pattern formation during development. The bullwinkle gene is required in Drosophila for disparate aspects of these processes. In females mutant at the bullwinkle...
