Insect Host Seeking: Investigations into the Molecular Mechanisms of Chemosensation
… The atypical odorant receptor gene, Or83b, is co-expressed with other ORs in most olfactory sensory neurons (OSNs) of the Drosophila antenna. OR83b acts as a generic heterodimeric partner for other ORs coupling them to the ciliary trafficking machinery, which is responsible for …

Functional and structural analyses of an olfactory receptor from Drosophila melanogaster
… in heterologous cells. The co–transfection of Or83b into S2 cells had no impact on these interactions, however Or83b is likely expressed in this cell line. Finally, models of how a ligand binding OR interacts physically with the ion channel Or83b are presented, and approaches that could be used …

Structure-Function Analysis of Insect Olfactory Receptors
… subunit and one constant subunit named OR83b (Benton et al., 2006). Insect ORs have historically been grouped with mammalian and nematode ORs, both of which are G protein coupled receptors (GPCRs), whose activation leads to increased concentrations of intracellular second messengers and …

Cracking the Odor Code: Molecular and Cellular Deconstruction of the Olfactory Circuit of Drosophila Larvae
… with the highly conserved olfactory co-receptor Or83b. Second, odor response profiles of 11 larval OSNs were characterized by calcium imaging. A subset of larval neurons showed overlapping responses to the set of odorants tested, while other neurons showed either very narrow or very broad tuning. …

Neuronal and Molecular Basis of Nociception and Thermosensation in Drosophila melanogaster
… These neurons express the olfactory co-receptor Or83b and are known to be olfactory neurons. Calcium oscillations triggered by cooling were detected in these neurons and they were terminated by warming. Severe behavioral defects in avoiding cool temperatures were found in animals lacking …

Mosquito Odorant Receptors: C-terminal Motifs, Subfamily Expansion, and Function
… bind odorants and those that are part of the Or83b subfamily. There is little informaiton on how heterodimers are formed and where within the protein heterodimer sites exist. The C-terminal region has been implicated as sites for such heterodimer formation. A hidden markov model based program, …
