Investigate the subcellular organization and molecular pathways governing synaptic growth at Drosophila neuromuscular synapses.
Mapped the subcellular localization of synaptic proteins, including FAS2, SIF, BetaPS integrin, DLG, and dynamin (SHI), relative to synaptic active zones in Drosophila.
Conducted genetic interaction and localization assays using sif and Fas2 mutants to evaluate their functional relationship during synaptic development.
FAS2, SIF, BetaPS integrin, and DLG localized specifically to the periactive zone surrounding the active zone, whereas the endocytic regulator SHI localized to a distinct domain.
Mutant analyses demonstrated that sif genetically interacts with Fas2 to regulate synaptic growth, with correct SIF localization dependent on FAS2.
Active zones and periactive zones segregated into distinct subcellular domains specialized for neurotransmission and synaptic growth, respectively.
