GMR regulatory sequences drive expression of a truncated form of Lar (composed of Lar amino acid residues 33-1406, an SL dipeptide (which does not interfere with Lar function) and Lar amino acid residues 1409-1470), lacking both phosphatase domains. The protein is tagged with Tag:SS(wg) and three copies of the Tag:HA at the N-terminus.
Expression of LarΔC.GMR.T:wg,T:Ivir\HA1 in a wild-type background does not disrupt the normal pattern of photoreceptor axon projections.
LarΔC.GMR.Tag:SS(wg),Tag:HA partially rescues LarC219
Partially rescues the R7 targeting defects of mosaic animals in which the retina is homozygous for LarC219.
