An 80 amino acid deletion that specifically removes the glutamine rich region from the A and B isoforms of orb2.
orb2Δ80Q mutant flies exhibit defects in learned courtship suppression. When orb2Δ80Q male flies are repeatedly exposed to the unreceptive female they suppress courtship for less than 24hr, compared with several days in wild type.
orb2Δ80Q mutant flies are defective in forming stable associative olfactory-reward memory. By 24 hours after training orb2Δ80Q mutant flies have a lower memory score than wild type flies.
