UAS regulatory sequences drive expression of a mutated form of Grip in which the conserved R/KxxxGLGF carboxylate binding loop motif of domain PDZD 3 has been mutated to AxxxGAGF.
ventral longitudinal muscle cell, with Gripex36, Scer\GAL4twi.PG
Scer\GAL4twi.PG/Gripx3.UAS partially rescues Gripex36
Expression of Gripx3.Scer\UAS under the control of Scer\GAL4twi.PG deos not fully rescue the ventrolateral muscle defects of Gripex36 mutants.
