UAS regulatory sequences drive expression of the F isoform of LpR2 in which the LA-2 domain has been tandemly duplicated. The protein is tagged at the C-terminal end with Tag:HA.
Expression of LpR2F+LA2.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4en-e16E does not rescue lipid accumulation in the posterior compartment of the wing disc in Df(3R)LpR1-2 animals.
