Amino acid replacement S512E, resulting in a phosphomimetic form of slpr.
Embryos expressing slprPXEP.Scer\UAS.P\T.T:Ivir\HA1 under the control of Scer\GAL4pnr-MD237 undergo dorsal closure, although mild puckering at the dorsal midline is seen.
Expression of slprPXEP.Scer\UAS.P\T.T:Ivir\HA1 under the control of Scer\GAL4pnr-MD237 results in narrowing of the scutellum and loss of scutellar bristles.
Female flies expressing slprPXEP.Scer\UAS.P\T.T:Ivir\HA1 under the control of Scer\GAL4arm.PS and raised at 25[o]C show significantly increased survival on exposure to 37[o]C heat shock compared to wild-type controls.
Expression of slprPXEP.Scer\UAS.P\T.T:Ivir\HA1 under the control of Scer\GAL4arm.PS significantly rescues the lethality of slprBS06 animals.
