Construct: Included within an 11kb XhoI-EcoRI fragment (compare to nonA+tXhR11). Amino acid 13 (a R) in the RNP2 of RRM2 is replaced by a Y. In addition amino acids 52, 54 and 56 (a M, E and I) in the RNP1 of RRM 1 are replaced by K, F and F, respectively.
In an otherwise nonA- background, viability is good, as is longevity. Animals can fly and exert good control over their general movements. Fails to rescue the optomotor blindness associated with nonA mutants. Light-on/light-off transient-less phenotype caused by nonA- is not rescued. Males sing in a mutant manner, with wildly polycyclic pulses.
