Pflugers Arch 454:749-58. 2007..Because pheromones are used by insects to trigger mating and other behaviors, these insights may herald new approaches to control behavior in pathogenic and agricultural pest insects...
Activation of the T1 neuronal circuit is necessary and sufficient to induce sexually dimorphic mating behavior in Drosophila melanogasterDavid S Ronderos
Department of Pharmacology, University of Texas Southwestern Medical Center, Dallas, Texas 75390 9111, USA
J Neurosci 30:2595-9. 2010..These findings demonstrate that the T1/Or67d circuit is necessary and sufficient to mediate sexually dimorphic courtship behaviors...
Activation of pheromone-sensitive neurons is mediated by conformational activation of pheromone-binding proteinJohn D Laughlin
Department of Pharmacology, University of Colorado at Denver and Health Sciences Center, 12801 East 17th Avenue, M S 8303, P O Box 6511, Aurora, CO 80045, USA
Cell 133:1255-65. 2008..Therefore, the pheromone-binding protein is an inactive, extracellular ligand converted by pheromone molecules into an activator of pheromone-sensitive neurons and reveals a distinct paradigm for detection of odorants...
SNMP is a signaling component required for pheromone sensitivity in DrosophilaXin Jin
Department of Pharmacology, University of Texas Southwestern Medical Center, 5323 Harry Hines Boulevard, Dallas, TX 75390 9111, USA
Proc Natl Acad Sci U S A 105:10996-1001. 2008..Therefore, pheromone perception in Drosophila should serve as an excellent model to elucidate the role of CD36 members in transmembrane signaling...
Drosophila R2D2 mediates follicle formation in somatic tissues through interactions with Dicer-1Savitha Kalidas
Department of Pharmacology, University of Texas Southwestern Medical Center, 5323 Harry Hines Boulevard Dallas, TX 75390 9111, USA
Mech Dev 125:475-85. 2008..We conclude that R2D2 functions beyond its role in RNA interference to include ovarian development in Drosophila...
A pheromone receptor mediates 11-cis-vaccenyl acetate-induced responses in DrosophilaTal Soo Ha
Department of Pharmacology and Center for Basic Neuroscience, University of Texas Southwestern Medical Center, Dallas, Texas 75390, USA
J Neurosci 26:8727-33. 2006..Here, we show LUSH are also required in non-T1 neurons misexpressing the receptor to respond to VA. These data provide new insight into the molecular components and neuronal basis of volatile pheromone perception...
Drosophila OBP LUSH is required for activity of pheromone-sensitive neuronsPingxi Xu
Department of Pharmacology, Center for Basic Neuroscience, University of Texas Southwestern Medical Center, 5323 Harry Hines Boulevard, Dallas, TX 75335, USA
Neuron 45:193-200. 2005..These studies directly link pheromone-induced behavior with OBP-dependent activation of a subset of olfactory neurons...
Diverse signaling mechanisms mediate volatile odorant detection in DrosophilaDavid S Ronderos
Department of Pharmacology, University of Texas Southwestern Medical Center, Dallas, TX, USA
Fly (Austin) 3:290-7. 2009..Some of these mechanisms have not been observed in other animals, suggesting they evolved relatively late along an evolutionary branch that ultimately gave rise to the insects...
LUMP is a putative double-stranded RNA binding protein required for male fertility in Drosophila melanogasterCharcacia Sanders
Department of Pharmacology and Neuroscience, University of Texas Southwestern Medical Center, Dallas, Texas, United States of America
PLoS ONE 6:e24151. 2011..We show that one dsRNA binding domains (dsRBD) is essential for LUMP function in male fertility. These findings reveal LUMP is a novel factor required for late stages of male germline differentiation...
Targeted mutation of a Drosophila odor receptor defines receptor requirement in a novel class of sensillumTamara Elmore
Department of Pharmacology and Center for Basic Neuroscience, University of Texas Southwestern Medical Center, Dallas, Texas 75390 9111, USA
J Neurosci 23:9906-12. 2003..These studies demonstrate that a reverse genetic approach can be used to correlate specific olfactory receptors with odor specificity of functional classes of olfactory neurons...
Insect odorant receptors: channeling scentTal Soo Ha
Department of Pharmacology, University of Texas Southwestern Medical Center, 5323 Harry Hines Boulevard, Dallas, TX 75390 9111, USA
Cell 133:761-3. 2008..Two recent studies in Nature (Sato et al., 2008; Wicher et al., 2008) now reveal that these OR-Or83b heterodimers form odorant-gated ion channels, revealing a surprising new mode of olfactory transduction...
R2D2, a bridge between the initiation and effector steps of the Drosophila RNAi pathwayQinghua Liu
Howard Hughes Medical Institute and Department of Biochemistry, University of Texas Southwestern Medical Center at Dallas, Dallas, TX 75390, USA
Science 301:1921-5. 2003..These results indicate that R2D2 bridges the initiation and effector steps of the Drosophila RNAi pathway by facilitating siRNA passage from Dicer to RISC...
Functional genomics, fragile X syndrome, and RNA interferenceSavitha Kalidas
Department of Pharmacology and Center for Basic Neuroscience, The University of Texas Southwestern Medical Center at Dallas, 75390-9111, USA
Arch Neurol 60:1197-200. 2003
Structure of a specific alcohol-binding site defined by the odorant binding protein LUSH from Drosophila melanogasterSchoen W Kruse
Department of Pharmacology, University of Colorado Health Sciences Center, M S C236, 4200 East Ninth Avenue, Denver, Colorado 80262, USA
Nat Struct Biol 10:694-700. 2003..Further, these sequences are found in regions of ion channels that are known to confer alcohol sensitivity. We suggest that the alcohol-binding site in LUSH represents a general model for alcohol-binding sites in proteins...
