General Information
Term adult olfactory receptor neuron Ir41a ID (Ontology) FBbt:00110015 (Fly Anatomy)
Definition Adult olfactory receptor neuron that expresses the Ionotropic receptor (Ir) 41a (FBgn0040849) and the co-receptors 25a (FBgn0031634) and 76b (FBgn0036937). Its dendrite transduces signals from the antennal coeloconic sensillum ac2 (Benton et al., 2009). It responds to polyamines (Benton et al., 2025). It innervates antennal lobe glomerulus VC5 (Schlegel et al., 2021) bilaterally (Kaur et al., 2019). It develops from an Nba precursor (Benton et al., 2025). There are approximately 12-13 of these cells on each side (Grabe et al., 2016; Benton et al., 2025).[ FlyBase:FBrf0206496 FlyBase:FBrf0233453 FlyBase:FBrf0243918 FlyBase:FBrf0249560 FlyBase:FBrf0262710 ]
Also Known As"ionotropic receptor neuron Ir41a" ; "Ir41a ac2" ; "ORN (VC5)" (for all, see Synonyms field below)
