The 2038bp '57F03' enhancer ( 3R:14102809..14104846 ) of the PK1-R gene drives expression of a lexA::GAD driver.
EcollexAGAD.57F03.Tag:NLS(SV40-largeT) positive adult ingestion neuron 1 directly interact with ScerGAL4Gr43a-GAL4 or ScerGAL4Gr64a.1.6 expressing S cells as shown by a positive GFP reconstitution across synaptic partners (GRASP) signal.
