Scer\GAL4Gr59a.1.5 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. Expression is also observed in projections to the abdominal ganglion.
Scer\GAL4Gr59a.1.5 is expressed in gustatory neurons of all of the bitter-sensitive short labellar taste bristles.
Scer\GAL4Gr59a.1.5 is expressed in all of the short bitter-sensitive sensilla of the labellum.
Scer\GAL4Gr59a.1.5 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\GAL4Gr58b.1, Scer\GAL4Gr59c.5.5 and Scer\GAL4Gr93b.5.3.
