UASt regulatory sequences drive expression of an inverted repeat.
Pre-synaptic expression of cacKK101478 under the control of Scer\GAL4elav-C155 and Scer\GAL4sca.PC diminishes evoked transmission at the larval NMJ compared with wild type controls. Muscle expression of cacKK101478 (under the control of Scer\GAL4C57) has no effect on neurotransmission.
Expression of cacKK101478 under the control of multiple pre- and post-synaptic drivers (Scer\GAL4elav-C155, Scer\GAL4sca.PC and Scer\GAL4C57) results in markedly decreased NMJ-evoked excitation and quantal content compared to controls.
Scer\GAL4C57, Scer\GAL4elav-C155, Scer\GAL4sca.PC, cacKK101478 has abnormal neurophysiology phenotype, enhanceable by GluRIICRNAi.UAS.cBa, Scer\GAL4C57, Scer\GAL4elav-C155, Scer\GAL4sca.PC
Expression of GluRIICdsRNA.Scer\UAS.cBa enhances the reduction in quantal size seen in the larval NMJ when cacKK101478 is expressed in multiple pre- and post-synaptic drivers (Scer\GAL4elav-C155, Scer\GAL4sca.PC and Scer\GAL4C57) alone. However, the defects in evoked transmission are not enhanced due to a compensatory increase in presynaptic quantal content.
