Expression of the first 88 amino acids of Src64B fused to the first 1151 amino acids of Sra-1 is under the control of UAS sequences.
adult head & macrochaeta, with Scer\GAL4sca.PC
trichogen cell & actin filament & pupa, with Scer\GAL4sca.PC
Sra-1ΔC.Scer\UAS.T:Myr1; Scer\GAL4sca.PC lack most head macrochaetae. Remaining macrochaetae are often bent. Actin filament bundles fail to form at the site of macrochaetae formation in pupae. Sra-1ΔC.Scer\UAS.T:Myr1; Scer\GAL4sca.PC flies lack many thoracic microchaetae.
Scer\GAL4sca.PC, CyfipΔC.UAS.Tag:Myr(Src64B) has thorax & microchaeta phenotype, suppressible | partially by HemUAS.Tag:Myr(Src64B), Scer\GAL4sca.PC
The loss of thoracic microchaetae in Sra-1ΔC.Scer\UAS.T:Myr1; Scer\GAL4sca.PC flies is suppressed by HemScer\UAS.T:Myr1, although the resulting bristles are frequently split.
