Imprecise excision of Mi{ET1}NetoMB07125 has resulted in a deletion ( X:13 ,521,082..13,524,084 (R6)), including part of exon 13 and 14 of Neto.
Neto203 mutant adult flies have no apparent defects.
The spontaneous miniature excitatory junctional potential (mEJP) amplitude and frequency are reduced in Neto203 mutant third instar larvae. Evoked EJP amplitude is slightly reduced. Quantal content is increased compared to controls.
Neto203 mutant NMJS have fewer but larger type Ib boutons. The enlarged Neto203 mutant boutons have diminished or absent subsynaptic reticulum (SSR) structures.
Neto203 mutant NMJs have an increased number of synaptic contacts, and their density is increased at proximal but not distal boutons.
The active zones of Neto203 mutant NMJs often have abnormal T-bar structures. Postsynaptic density (PSD) length is significantly reduced compared to controls.
