Adults homozygous for Ir52cMB04402 do not have significant changes in proboscis extension rates in response to fatty acids, but do have a significant increase in response to sucrose, compared to controls.
Ir52cMB04402 mutant male flies exhibit a moderate but significant copulation delay phenotype. No courtship defects are observed.
Ir52cMB04402 is rescued by Ir52c+tIr52rescueC
Expression of Ir52c+tIr52rescueC rescues the copulation delay seen in Ir52cMB04402 mutant males.
