Scer\GAL4Gr58b.1 drives expression in larval gustatory receptor neuron of the epiphysis DP1, where it is coexpressed with Scer\GAL4Gr33a.4.7, Scer\GAL4Gr66a.1.8, Scer\GAL4Gr93a.5, Scer\GAL4Gr32a.3.7.PW, Scer\GAL4Gr22b.5.8, Scer\GAL4Gr39a.a.3.4, Scer\GAL4Gr39b.4.4, Scer\GAL4Gr22d.3.1, Scer\GAL4Gr39b.4.4, Scer\GAL4Gr22e.2.5, Scer\GAL4Gr28b.a.3, Scer\GAL4Gr39a.b.1, and Scer\GAL4Gr59d.4.1.
Scer\GAL4Gr58b.1 is expressed in gustatory neurons of 6 of the bitter-sensitive short labellar taste bristles.
Scer\GAL4Gr58b.1 is expressed in a few of the short bitter-sensitive sensilla of the labellum.
Scer\GAL4Gr58b.1 drives expression in one neuron of the larval terminal organ. This neuron co-expresses Scer\GAL4Gr33a.4.7, Scer\GAL4Gr66a.1.8, Scer\GAL4Gr32a.3.7.PW, Scer\GAL4Gr39a.a.3.4, Scer\GAL4Gr39a.b.1, Scer\GAL4Gr59d.4.1, Scer\GAL4Gr22a.4.2, Scer\GAL4Gr22e.2.5, Scer\GAL4Gr28b.a.3, Scer\GAL4Gr28b.e.4.245, Scer\GAL4Gr36b.0.9, Scer\GAL4Gr36c.2.5, Scer\GAL4Gr9a.6.3, Scer\GAL4Gr59a.1.5, Scer\GAL4Gr59c.5.5 and Scer\GAL4Gr93b.5.3. Expression of Scer\GAL4Gr58b.1 is also detected in one neuron of the dorsal pharyngeal sense organ (DPS or epiphysis).
