Flying insects are well known for airborne odour tracking and have evolved diverse
chemoreceptors. While ionotropic receptors (IRs) are found across protostomes, insect …

In many moths, mate-finding communication is mediated by the female sex pheromones.
Since differentiation of sex pheromones is often associated with speciation, it is intriguing to …

In many species, olfactory transduction is triggered by odorant molecules that interact with
olfactory receptors coupled to heterotrimeric G-proteins. The role of G-protein–linked …

Intracellular signaling in insect olfactory receptor neurons remains unclear, with both
metabotropic and ionotropic components being discussed. Here, we investigated the role of …

Insects have a remarkable capacity to sense a wide range of volatile chemicals in their
environment with high sensitivity and specificity. Chemical cues originating from various …

Background Seven-transmembrane receptors typically mediate olfactory signal transduction
by coupling to G-proteins. Although insect odorant receptors have seven transmembrane …

The sex pheromone receptors (SPRs) of Lepidopteran insects play important roles in
chemical communication. In the sex pheromone detection processes, sex pheromone …

Insect molting is an important developmental process of metamorphosis, which is initiated by
molting hormone. Molting includes the activation of dermal cells, epidermal cells separation …

In insects, antennal ionotropic receptors (IRs) and odorant receptors (ORs) are among the
main sensors of olfactory cues. To functionally characterize the subunits from these …

G protein β subunit 1 (GNβ1) has several functions, including cell growth regulation, the
control of second messenger levels, and ion channel switching. Previous transcriptome …
