General Information

Term

adult doublesex TN2 (male) neuron

ID (Ontology)

FBbt:00047364 (Fly Anatomy)

Definition

Doublesex-expressing neuron of the adult that has its cell body in the ventral nerve cord, outside of the TN1 cluster. Based on the wide distribution of these cells throughout the thoracic neuromeres, this class may comprise several unrelated subgroups (Lee et al., 2002). This type of neuron disappears during pupal development in the female (Rideout et al., 2010).[ FlyBase:FBrf0159058 FlyBase:FBrf0210397 FlyBase:FBrf0210735 FlyBase:FBrf0234085 ]

Also Known As

"doublesex-expressing Thoracic Neuron-2" ; "dsx-expressing Thoracic Neuron-2" ; "dsx-TN2"
