General Information
Term adult olfactory receptor neuron Ir92a ID (Ontology) FBbt:00110012 (Fly Anatomy)
Definition Adult olfactory receptor neuron that expresses the Ionotropic receptor (Ir) 92a and the co-receptors Ir25a and Ir76b (Benton et al., 2025). Its axon innervates antennal lobe glomerulus VM1, bilaterally, fasciculating with the antennal lobe commissure (Silbering et al., 2011; Kaur et al., 2019). Its dendrite transduces signals from antennal coeloconic sensillum ac1 (Benton et al., 2009) and it responds to ammonia (Min et al., 2013). It develops from an Nba precursor (Benton et al., 2025). There are approximately 15 of these cells on each side (Grabe et al., 2016).[ FlyBase:FBrf0206496 FlyBase:FBrf0215822 FlyBase:FBrf0221182 FlyBase:FBrf0233453 FlyBase:FBrf0243918 FlyBase:FBrf0262710 ]
Also Known As "adult olfactory receptor neuron Ir76b/92a" ; "ionotropic receptor neuron Ir92a" ; "Ir92a ac1" (for all, see Synonyms field below)
