Amino acid replacement: Q71L.
UASt regulatory sequences drive expression of dnd coding sequences with a point mutation that is expected to disrupt GTP hydrolysis, resulting in a constitutively active form of the protein.
Scer\GAL4esg-p127/dndQ71L.UAS.cJa partially rescues dndd10234
Scer\GAL4p127 driven expression of dndQ71L.Scer\UAS.cJa rescues the tracheal dorsal branch fusion defects found in dndd10234 mutant embryos from 20% to 85% fused.
