Description

UAS regulates expression of Spt-I (using cDNA clone RE58623) containing a C129W mutation homologous to a mutation in human SPT subunits SPTLC1/SPTLC2 associated with the HSAN-1 disorder, and tagged with 3x Tag:HA at the C-terminus.

      Reference

      Expressing Spt-IC129W.UAS.Tag:HA under the control of Scer\GAL4Act5C.PI, but not Scer\GAL4ey-OK107, leads to a low prevalence of axon branch segregation defects of mushroom body neurons.
