General Information
Term adult pheromone-sensing fru neuron of prothoracic leg (male) ID (Ontology) FBbt:00052290 (Fly Anatomy)
Definition Male-specific gustatory receptor neuron of the prothoracic leg that expresses ppk23 and fruitless (Thistle et al., 2012; Toda et al., 2012). It detects pheromones and is involved in stimulating male courtship of females and inhibiting courtship of males (Thistle et al., 2012; Toda et al., 2012). There are approximately 32 of these cells on each side (Toda et al., 2012).[ FlyBase:FBrf0218411 FlyBase:FBrf0218960 ]
Also Known As "male ppk23+fru+ neuron"
Comment No fru/ppk23 cells in T2 or T3 legs (Toda et al., 2012) or proboscis (Thistle et al., 2012) or female T1 legs (Toda et al., 2012). Includes some cells that detect female pheromones (Toda et al., 2012) and some that detect male pheromones (Zhang et al., 2022 - FBrf0252940).
