Additional Information
Statement
Reference

ScerGAL4Gr89a.2 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)

ScerGAL4Gr89a.2 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)

ScerGAL4Gr89a.2 is strongly expressed in almost all of the short and intermediate taste sensilla of the labellum.
