      ScerGAL4Gr39a.b.1 drives expression in 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, ScerGAL4Gr39a.a.3.4, ScerGAL4Gr39b.4.4, ScerGAL4Gr22d.3.1, ScerGAL4Gr39b.4.4, ScerGAL4Gr22e.2.5, ScerGAL4Gr28b.a.3, ScerGAL4Gr58b.1, and ScerGAL4Gr59d.4.1.

      (Choi et al., 2016)

      ScerGAL4Gr39a.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.

      (Park and Kwon, 2011)

      ScerGAL4Gr39a.b.1 is expressed in gustatory neurons of 6 of the bitter-sensitive short labellar taste bristles.

      (Weiss et al., 2011)

      ScerGAL4Gr39a.b.1 expresses the isoform Gr39a-RB which is found in some of the short bitter-sensitive sensilla of the labellum.

      ScerGAL4Gr39a.b.1 is expressed in some of the short bitter-sensitive sensilla of the labellum.

      (Weiss et al., 2011)

      ScerGAL4Gr39a.b.1 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.a.3.4, 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 and ScerGAL4Gr59d.4.1. Expression of ScerGAL4Gr39a.a.3.4 is also detected in one neuron of the dorsal pharyngeal sense organ (DPS or epiphysis).
