ORN_V
ID: FBbt_00067064
Adult unilateral odorant receptor neuron that expresses Gr21a and Gr63a (Couto et al., 2005; Kwon et al., 2007; Kaur et al., 2019; Benton et al., 2025). It responds to CO2 levels (Suh et al., 2004; Kwon et al., 2007. Its dendrite transduces signals from antennal basiconic sensillum ab1 and sends output to antennal glomerulus V (Benton et al., 2025). It develops from an Nbb precursor (Benton et al., 2025). There are around 30-40 of these cells on each side (Grabe et al., 2016; Benton et al., 2025). (Suh et al., 2004, Stocker et al., 1990, Kaur et al., 2019, Couto et al., 2005, Grabe et al., 2016, Kwon et al., 2007)
Gr21a and Gr63a are only found in one ORN type and they are co-expressed (Kwon et al., 2006).
