Cytology
Description

2385bp of robo1 upstream flanking sequence drives expression of robo1 lacking the Ig2 domain (amino acid residues 153-252 are missing). 2192bp of robo1 downstream flanking sequence is also present. The protein produced contains the endogenous robo1 signal peptide and is tagged with 4 copies of Tag:HA directly upstream of the first Ig domain present (Ig1).

      Detailed Description
      Statement
      Reference

      Expression of robo1ΔIg2.T:Ivir\HA1 in the wild-type background has no discernible effect on the structure and morphology of the embryonic ventral nerve cord, not even when two copies of the transgene are present.

      The midline collapse phenotype observed in the ventral nerve cord of embryos expressing comm10xScer\UAS.cRa under the control of Scer\GAL4elav.PLu is not affected by combination with robo1ΔIg2.T:Ivir\HA1.

      robo1ΔIg2.Tag:HA partially rescues robo11

      (Reichert et al., 2016)
      Comments

      Expression of robo1ΔIg2.T:Ivir\HA1 in robo11 mutant background strongly rescues the defects in midline repulsion characteristic for robo11 embryos but the fraction of segments with axons ectopically crossing the ventral cord midline is still increased compared to controls.
