The attP cassette in the Mi{MIC}RluA-1MI06897 insertion has been replaced with a Trojan GAL4 cassette that contains a splice acceptor site followed by the T2A peptide, the GAL4 coding sequence and an Hsp70 transcription termination signal. Thus GAL4 expression is driven by the native RluA-1 regulatory sequences.
Comment: axonal projections
Reporter expression is observed in the peripheral sensory neurons in each segment of the larval body wall. In the dorsal cluster, signal was detected in the cell body and dendrites of all four classes of multidendritic neurons, dorsal multiple dendrite neuron dmd1, external sensory and dorsal bipolar dendritic neurons. In the ventral nerve cord, signal is seen in axonal projections of the sensory neurons. In the adult brain, significant signal was observed in the optic lobes and in small clusters in the central brain.
