Molecular Scaffolds in Drosophila Signal Transduction

细胞通讯是所有多细胞生物正常发育的关键过程。发育生物学研究的一个重要焦点是了解细胞如何整合不同类型的信号，以在发育生物体的背景下做出适当的细胞命运决定。目前的研究表明，作为分子支架和接头的蛋白质在整合细胞内的信号事件中起着至关重要的作用。这些支架通过组装多蛋白复合物来确保细胞内信号成分的正确路径。Veraksa博士研究的长期目标是阐明这种蛋白质适配器如何控制细胞通讯。研究表明，在哺乳动物系统中，阻滞蛋白起着分子支架的作用。Veraksa博士的实验室将研究arretin如何控制果蝇（Drosophila melanogaster）胚胎中的细胞信号传导。他们将结合传统的遗传方法和更先进的方法来研究这些胚胎中蛋白质之间的相互作用。Veraksa博士的实验室为培养来自不同背景的遗传学和分子发育的研究生和本科生提供了良好的环境。这项研究的完成将促进我们在分子水平上对细胞通讯的理解。

Cell communication is a key process during normal development of all multicellular organisms. An important focus of developmental biology research is to understand how cells integrate different types of signals to make appropriate cell fate decisions in the context of developing organisms. Current research indicates proteins that serve as molecular scaffolds" and adaptors play a vital role in integrating signaling events within cells. These scaffolds act by assembling multi-protein complexes that ensure proper routing of signaling components inside cells. The long-term goal of Dr. Veraksa's research is to elucidate how such protein adaptors control cell communication. It has been shown that Arrestin proteins act as molecular scaffolds in mammalian systems. Dr. Veraksa's laboratory will investigate how Arrestin controls cell signaling in embryos of the fruit fly, Drosophila melanogaster. They will use a combination of traditional genetic approaches and more advanced methods to study protein-protein interactions in these embryos. Dr. Veraksa's laboratory provides an excellent environment for training graduate and undergraduate students from diverse backgrounds in genetics and molecular development. Completion of the proposed research will advance our understanding of cell communication at the molecular level.
