UAS governs expression of a hbs/sns 'domain swap' chimeric protein which includes the hbs ectodomain with the sns transmembrane and cytodomains. There is also a C-terminal Tag:HA tag.
hbs::snsUAS.HESTC.Tag:HA/Scer\GAL4sns.PK is a suppressor of embryonic myoblast phenotype of snsZF1.4
Scer\GAL4sns.PK-mediated expression of hbs::snsScer\UAS.HESTC.T:Ivir\HA1 rescues the snsZF1.4 myoblast fusion phenotype.
