(Choi et al., 2016)

ScerGAL4Gr39b.4.4 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.

(Park and Kwon, 2011)

ScerGAL4Gr39b.4.4 is expressed in gustatory neurons of 4 of the bitter-sensitive short labellar taste bristles.

(Weiss et al., 2011)

ScerGAL4Gr39b.4.4 is expressed in a few of the short bitter-sensitive sensilla of the labellum.

(Weiss et al., 2011, Weiss et al., 2011)

ScerGAL4Gr39a.d.1.7 drives expression in two gustatory receptor neurons of the larval posterior pharyngeal sense organ (PPS or hypopharyngeal sense organ) and in one neuron of the dorsal pharyngeal sense organ (DPS or epiphysis).
