Scer\GAL4Gr39a.b.1 drives expression in adult abdominal multidendritic neurons with with dorsal processes extending along the left-right axis, as well as in multidendritic neurons with lateral processes extending anteroposteriorly; these major processes have several protruding dendrites. Additionally, expression is driven in laterally localized multidendritic neurons with extensive arborization. Expression is also observed in projections to the abdominal ganglion.

Scer\GAL4Gr39a.b.1 is expressed in gustatory neurons of 6 of the bitter-sensitive short labellar taste bristles.

Scer\GAL4Gr39a.b.1 expresses the isoform Gr39a-RB which is found in some of the short bitter-sensitive sensilla of the labellum.

Scer\GAL4Gr39a.b.1 is expressed in some of the short bitter-sensitive sensilla of the labellum.

Scer\GAL4Gr39a.b.1 drives expression in two gustatory receptor neurons of the larval terminal organ. One of these neurons also expresses Scer\GAL4Gr33a.4.7, Scer\GAL4Gr66a.1.8, Scer\GAL4Gr32a.3.7.PW, Scer\GAL4Gr28b.e.4.245, Scer\GAL4Gr36c.2.5, Scer\GAL4Gr39a.a.3.4, Scer\GAL4Gr59d.4.1, Scer\GAL4Gr9a.6.3, Scer\GAL4Gr22e.2.5, Scer\GAL4Gr22a.4.2, Scer\GAL4Gr28b.a.3, Scer\GAL4Gr36b.0.9, Scer\GAL4Gr58b.1, Scer\GAL4Gr59a.1.5, Scer\GAL4Gr59c.5.5 and Scer\GAL4Gr93b.5.3. The other terminal organ neuron co-expresses Scer\GAL4Gr33a.4.7, Scer\GAL4Gr66a.1.8 and Scer\GAL4Gr59d.4.1. Expression of Scer\GAL4Gr39a.a.3.4 is also detected in one neuron of the dorsal pharyngeal sense organ (DPS or epiphysis).
