Molecular evolution of Drosophila odorant receptor genes.
A total of 752 odorant receptor (Or) genes, including pseudogenes, were identified in 11 Drosophila species and named after their orthologs in Drosophila melanogaster. The 813 Or genes, including 61 from D. melanogaster, were classified into 59 orthologous groups that are well supported by gene phylogeny. By reconciling with the gene family phylogeny, we estimated the number of gene duplication...
متن کاملCommon Promoter Elements in Odorant and Vomeronasal Receptor Genes
In mammals, odorants and pheromones are detected by hundreds of odorant receptors (ORs) and vomeronasal receptors (V1Rs and V2Rs) expressed by sensory neurons that are respectively located in the main olfactory epithelium and in the vomeronasal organ. Even though these two olfactory systems are functionally and anatomically separate, their sensory neurons show a common mechanism of receptor gen...
متن کاملRegulatory Features for Odorant Receptor Genes in the Mouse Genome
The odorant receptor genes, seven transmembrane receptor genes constituting the vastest mammalian gene multifamily, are expressed monogenically and monoallelicaly in each sensory neuron in the olfactory epithelium. This characteristic, often referred to as the one neuron-one receptor rule, is driven by mostly uncharacterized molecular dynamics, generally named odorant receptor gene choice. Much...
متن کاملConsidering Nuclear Compartmentalization in the Light of Nuclear Dynamics
Many proteins are concentrated in compartments within the nucleus. Chromatin is also compartmentalized at different nuclear sites. However, nuclear proteins have now been shown to be highly mobile. This review considers the formation and function of nuclear compartments in a situation in which proteins are rapidly moving through the nuclear volume.
متن کاملMammalian odorant receptor tuning breadth persists across distinct odorant panels
The molecular receptive range (MRR) of a mammalian odorant receptor (OR) is the set of odorant structures that activate the OR, while the distribution of these odorant structures across odor space is the tuning breadth of the OR. Variation in tuning breadth is thought to be an important property of ORs, with the MRRs of these receptors varying from narrowly to broadly tuned. However, defining t...
