Drives expression in DN1 neurons and DN1p neurons. The 4.1M insertion (BDSC stock #36316) drives expression in DN1p neurons, while the 4.5F insertion (BDSC stock #37526) drives expression in all DN1 neurons.
GFP reconstitution across synaptic partners (GRASP) using ScerGAL4Clk.4.1M in combination with EcollexAPdf.cSa.T:HsimVP16 shows expression at the most distal part of s-LNv dorsal projections, ventral to DN1p neuron cell bodies.
ScerGAL4Clk.4.5F labels 8 to 10 posterior DN1 neurons.
