Visual transduction in Drosophila.
The Drosophila phototransduction cascade has emerged as an attractive paradigm for understanding the molecular mechanisms underlying visual transduction, as well as other G protein-coupled signaling cascades that are activated and terminated with great rapidity. A large collection of mutants affecting the fly visual cascade have been isolated, and the nature and function of many of the affected...
متن کاملA Drosophila mechanosensory transduction channel.
Mechanosensory transduction underlies a wide range of senses, including proprioception, touch, balance, and hearing. The pivotal element of these senses is a mechanically gated ion channel that transduces sound, pressure, or movement into changes in excitability of specialized sensory cells. Despite the prevalence of mechanosensory systems, little is known about the molecular nature of the tran...
متن کاملA novel protein encoded by the inad gene regulates recovery of visual transduction in drosophila
InaDp215 is a point mutation that affects photoreceptor function in Drosophila. To understand the molecular basis of the defect, we isolated the InaD gene and found it encodes a photoreceptor-specific polypeptide of 674 residues. Within its sequence are two repeats that share remarkable homology with a family of cytoskeleton-associated proteins that are involved in signal transduction. Patch-cl...
متن کاملThe Drosophila visual system
A compact genome and a tiny brain make Drosophila the prime model to understand the neural substrate of behavior. The neurogenetic efforts to reveal neural circuits underlying Drosophila vision started about half a century ago, and now the field is booming with sophisticated genetic tools, rich behavioral assays, and importantly, a greater number of scientists joining from different backgrounds...
متن کاملVisual circuit assembly in Drosophila.
Both insect and vertebrate visual circuits are organized into orderly arrays of columnar and layered synaptic units that correspond to the array of photoreceptors in the eye. Recent genetic studies in Drosophila have yielded insights into the molecular and cellular mechanisms that pattern the layers and columns and establish specific connections within the synaptic units. A sequence of inductiv...
