ScerGAL4Gr93b.5.3 drives expression in larval gustatory receptor neuron of the epiphysis DP2 where it is coexpressed with ScerGAL4Gr33a.4.7, ScerGAL4Gr66a.1.8, ScerGAL4Gr32a.3.7.PW and ScerGAL4Gr77a.4.
ScerGAL4Gr93b.5.3 is expressed in gustatory neurons of 5 of the bitter-sensitive short labellar taste bristles.
ScerGAL4Gr93b.5.3 is expressed in some of the short bitter-sensitive sensilla of the labellum.
ScerGAL4Gr93b.5.3 drives expression in one gustatory receptor neuron of the larval terminal organ. This neuron co-expresses ScerGAL4Gr33a.4.7, ScerGAL4Gr66a.1.8, ScerGAL4Gr32a.3.7.PW, ScerGAL4Gr28b.e.4.245, ScerGAL4Gr39a.a.3.4, ScerGAL4Gr39a.b.1, ScerGAL4Gr59d.4.1, ScerGAL4Gr9a.6.3, ScerGAL4Gr22e.2.5, ScerGAL4Gr22a.4.2, ScerGAL4Gr28b.a.3, ScerGAL4Gr36b.0.9, ScerGAL4Gr36c.2.5, ScerGAL4Gr58b.1, ScerGAL4Gr59a.1.5, ScerGAL4Gr59c.5.5 and ScerGAL4Gr93b.5.3 Expression of ScerGAL4Gr93b.5.3 is also detected in one neuron of the dorsal pharyngeal sense organ (DPS or epiphysis).
