Flies show an aberrant gravitaxic response in a vertical gravitaxic maze assay, and show wild type behaviour in a horizontal maze. Male courtship activity is comparable to wild type, and flight is not seriously impaired.
yuric263 is rescued by yuriUAS.cAa/Scer\GAL4yuri-c263
Scer\GAL4yuri-c263-mediated expression of yuriScer\UAS.cAa rescues the aberrant gravitaxic behaviour of yuric263 flies.
