Scer\GAL4Gr28a.PT drives expression in the following series of neurons. Larval gustatory receptor neuron of the hypophysis VP3, where it may coexpress with Scer\GAL4Gr68a.PB, VP4 and VP5. Larval gustatory receptor neuron of the hypopharyngeal organ PP3 where it is coexpressed with Scer\GAL4Gr33a.4.7, Scer\GAL4Gr66a.1.8, Scer\GAL4Gr32a.3.7.PW, Scer\GAL4Gr22b.5.8, Scer\GAL4Gr39a.a.3.4, Scer\GAL4Gr39b.4.4, Scer\GAL4Gr39a.d.1.7, Scer\GAL4Gr93c.3.8 and Scer\GAL4Gr93d.2.4 Larval gustatory receptor neuron of the hypopharyngeal organ PP4 where it is coexpressed with Scer\GAL4Gr33a.4.7, Scer\GAL4Gr66a.1.8, Scer\GAL4Gr22b.5.8, Scer\GAL4Gr39a.a.3.4, Scer\GAL4Gr39b.4.4, Scer\GAL4Gr39a.d.1.7, Scer\GAL4Gr93c.3.8 and Scer\GAL4Gr93d.2.4. Larval gustatory receptor neuron of the hypopharyngeal organ PP5 and PP6 where it is coexpressed with Scer\GAL4Gr93d.2.4.

Scer\GAL4Gr28a.PT 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 multidendritic neurons with ladder-like processes along the dorsal abdominal wall.

Scer\GAL4Gr28a.PT is expressed in gustatory neurons of all of the bitter-sensitive small labellar taste bristles, and in gustatory neurons of the three posterior-most intermediate labellar taste bristles.

Scer\GAL4Gr28a.PT is expressed in all of the short and in a few of the intermediate bitter-sensitive sensilla of the labellum.

Scer\GAL4Gr28a.PT drives expression in two gustatory receptor neurons of the larval terminal organ, two neurons of the dorsal organ, two neurons of the posterior pharyngeal sense organ (PPS or hypopharyngeal sense organ) and in two neurons of the ventral pharyngeal sense organ (VPS or hypophysis). The two neurons of the dorsal organ also express Scer\GAL4Gr2a.2.2.

Expression of Scer\GAL4Gr28a.PT is seen in approximately 32 neurons per labial palp. Scer\GAL4Gr28a.PT is found to be expressed in a single neuron associated with the ventral cibarial sense organ. Expression of Scer\GAL4Gr28a.PT is seen in two neurons associated with the fifth tarsal segment of the adult foreleg. Expression of Scer\GAL4Gr28a.PT is seen in a single, large cell at the base of the maxillary palpus that is not an olfactory sensory neuron. Expression is seen in leg neurons thought to be stretch receptors or proprioreceptors. In the larva, expression is seen in a single neuron per ventral pit of the terminal organ.
