ORN_VA7l [FBbt_00067052]

Adult olfactory receptor neuron (ORN) that expresses Or46aA and has its sensory dendrite in maxillary palp basiconic sensillum pb2 (Benton et al., 2025). It responds to phenol and methylphenols (Benton et al., 2025). Its axon innervates antennal lobe glomerulus VA7l, bilaterally (Benton et al., 2025). It expresses sNPF (Carlsson et al., 2010). It develops from an Nab precursor (Benton et al., 2025). There are approximately 8-12 of these cells on each side (Grabe et al., 2016; Benton et al., 2025).

Adult Nervous system Olfactory system Peptidergic Sensory neuron

Or46aB transcript is produced, but remains nuclear and is not spliced correctly to produce a functional receptor (Benton et al., 2025).
