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