Amino acid replacement: T31N.
UASt regulatory sequences drive expression of dnd with a point mutation that is expected to abolish GTP binding, thus yielding an inactive protein.
dndT31N.UAS.cJa/Scer\GAL4esg-p127 partially rescues dndd10234
Scer\GAL4p127 driven expression of dndT31N.Scer\UAS.cJa rescues the tracheal dorsal branch fusion defects found in dndd10234 mutant embryos from 20% to 41% fused.
