ScerGAL4Gr39a.a.3.4 drives expression in the following series of neurons. Larval gustatory receptor neuron of the epiphysis DP1, where it is coexpressed with ScerGAL4Gr33a.4.7, ScerGAL4Gr66a.1.8, ScerGAL4Gr93a.5, ScerGAL4Gr32a.3.7.PW, ScerGAL4Gr22b.5.8, ScerGAL4Gr39b.4.4, ScerGAL4Gr9a.6.3, ScerGAL4Gr22d.3.1, ScerGAL4Gr22e.2.5, ScerGAL4Gr28b.a.3, ScerGAL4Gr39a.b.1, ScerGAL4Gr58b.1, and ScerGAL4Gr59d.4.1. Larval gustatory receptor neuron of the hypopharyngeal organ PP1 and PP2 where it is coexpressed with ScerGAL4Gr33a.4.7, ScerGAL4Gr66a.1.8, ScerGAL4Gr32a.3.7.PW, ScerGAL4Gr22b.5.8, ScerGAL4Gr39b.4.4, ScerGAL4Gr39a.d.1.7, ScerGAL4Gr93c.3.8 and ScerGAL4Gr93d.2.4. Larval gustatory receptor neuron of the hypopharyngeal organ PP3 where it is coexpressed with ScerGAL4Gr33a.4.7, ScerGAL4Gr66a.1.8, ScerGAL4Gr32a.3.7.PW, ScerGAL4Gr28a.PT, ScerGAL4Gr22b.5.8, ScerGAL4Gr39b.4.4, ScerGAL4Gr39a.d.1.7, ScerGAL4Gr93c.3.8 and ScerGAL4Gr93d.2.4 Larval gustatory receptor neuron of the hypopharyngeal organ PP4 where it is coexpressed with ScerGAL4Gr33a.4.7, ScerGAL4Gr66a.1.8, ScerGAL4Gr28a.PT, ScerGAL4Gr22b.5.8, ScerGAL4Gr39b.4.4, ScerGAL4Gr39a.d.1.7, ScerGAL4Gr93c.3.8 and ScerGAL4Gr93d.2.4.

(Choi et al., 2016)

ScerGAL4Gr39a.a.3.4 is expressed in gustatory neurons of all of the bitter-sensitive short labellar taste bristles, and in gustatory neurons of all of the intermediate labellar taste bristles.

(Weiss et al., 2011)

ScerGAL4Gr39a.a.3.4 expresses the isoform Gr39a-RA which is found in all the short and intermediate bitter-sensitive sensilla of the labellum.

(Weiss et al., 2011)

ScerGAL4Gr39a.a.3.4 is expressed in all the short and intermediate bitter-sensitive sensilla of the labellum.

(Weiss et al., 2011)

ScerGAL4Gr39a.a.3.4 drives expression in two gustatory receptor neurons of the larval terminal organ. One of these neurons also expresses ScerGAL4Gr33a.4.7, ScerGAL4Gr66a.1.8, ScerGAL4Gr32a.3.7.PW, ScerGAL4Gr28b.e.4.245, ScerGAL4Gr36c.2.5, ScerGAL4Gr39a.b.1, ScerGAL4Gr59d.4.1, ScerGAL4Gr9a.6.3, ScerGAL4Gr22e.2.5, ScerGAL4Gr22a.4.2, ScerGAL4Gr28b.a.3, ScerGAL4Gr36b.0.9, ScerGAL4Gr58b.1, ScerGAL4Gr59a.1.5, ScerGAL4Gr59c.5.5 and ScerGAL4Gr93b.5.3. The other terminal organ neuron co-expresses ScerGAL4Gr33a.4.7, ScerGAL4Gr66a.1.8, ScerGAL4Gr57a.6, ScerGAL4Gr59d.4.1, ScerGAL4Gr47b.2 and ScerGAL4Gr94a.3.7. Expression of ScerGAL4Gr39a.a.3.4 is also detected in one neuron of the dorsal pharyngeal sense organ (DPS or epiphysis) and two neurons of the posterior pharyngeal sense organ (PPS or hypopharyngeal sense organ).
