UAS regulatory sequences drive expression of a fusion protein consisting of Sdc in which the transmembrane domain has been replaced by the transmembrane domain of Hsap\PDGFRB (which lacks dimerisation ability, in contrast to that of Sdc). The protein is tagged in the extracellular domain with a 5x Tag:MYC tag.
Expression of Sdc::Hsap\PDGFRBTM-Swap.Scer\UAS.T:Hsap\MYC driven post-synaptically by Scer\GAL4how-24B leads to a significant increase in the number of boutons per neuromuscular junction, compared to controls.
Scer\GAL4how-24B/Sdc::Hsap\PDGFRBTM-Swap.UAS.Tag:MYC is a suppressor of abnormal neuroanatomy | third instar larval stage phenotype of Sdc10608/Df(2R)48
Scer\GAL4how-24B/Sdc::Hsap\PDGFRBTM-Swap.UAS.Tag:MYC is a suppressor of NMJ bouton | third instar larval stage phenotype of Sdc10608/Df(2R)48
Sdc10608/Df(2R)48 third instar larvae (in which Sara function has been rescued by SaraUbi.PJ) have a decrease in the number of boutons per neuromuscular junction, compared to controls; this phenotype is rescued by expression of Sdc::Hsap\PDGFRBTM-Swap.Scer\UAS.T:Hsap\MYC driven by Scer\GAL4how-24B.
