A 1995bp fragment from immediately upstream of the Ir75d start codon is fused upstream of sequence encoding a GAL4 driver.
ScerGAL4Ir75d.1995 is expressed in the olfactory receptor neurons Ir75d ac1, Ir75d ac2, Ir75d ac4 that innervate the antennal coeloconic sensillum ac1, ac2 and ac4 and project to the antennal lobe glomeruli VL1.
