ScerGAL4Mmp2-NP0509 drives expression in around 9 laterally positioned adult multiglomerular antennal lobe projection neurons innervating all antennal lobe glomeruli and the antennal lobe hub.
Mmp2 reporter is expressed in the air sac primordium in third instar larvae and becomes progressively more prominent at the distal end of the air sac and in the tip cells.
Only weak expression of Mmp2 reporter is observed at late pupal stages. Expression is significantly elevated at the early adult stage (0-4 hr after eclosion) and returns to the basal level three days after eclosion. Mmp2 appears to be transiently upregulated in epithelial cells during 24 hours after eclosion.
Blockade of PNv2 (by expressing the temperature sensitive shits.UAS.cUa under the control of Scer\GAL4NP0509 and shifted to the permissive 33[o]C) abolishes odor acuity.
