UAS regulatory sequences drive expression of the C-terminal part of Abp1 (including the SH3 domain), which is tagged with a myristoylation motif (Tag:Myr(Src64B)).
Expression of Abp1C-term.Scer\UAS.T:Myr-Src64B under the control of Scer\GAL4sca.PU results in a split microchaete phenotype. The split microchaete phenotype is accompanied by a reduction in microchaete length.
