Amino acid replacement: R87A.
UAS regulatory sequences drive expression of a mutated form of Grip. The mutations disrupt the conserved carboxylate binding loop motif of domain PDZD 1.
Amino acid replacement: L92A.
lateral transverse muscle cell, with Scer\GAL4twi.PG
Larvae expressing Gripx1.Scer\UAS under the control of Scer\GAL4twi.PG show ectopic lateral transverse muscle projections.
