Imprecise excision of the progenitor insertion, resulting in a deletion that removes the majority of the cdm coding sequence.
The number of synaptic boutons per muscle area is normal at the third larval instar cdm164 neuromuscular junction, although there is a small decrease in the total surface area of muscles 6 and 7 compared to controls. The number of active zones and the length of the postsynaptic density are normal. The ratio of subsynaptic reticulum (SSR) per bouton area and the SSR density are reduced compared to controls.
The amplitude and frequency of miniature excitatory junctional potentials at the larval neuromuscular junction is normal in homozygous cdm164 and cdm164/Df(3R)DG2 animals.
At 2mM extracellular Ca[2+], the evoked excitatory junctional potential (EJP) at the larval neuromuscular junction is normal in homozygous cdm164 and cdm164/Df(3R)DG2 animals. At low concentrations (0.35mM and 0.5mM) extracellular Ca[2+], the amplitude of the evoked EJP at the larval neuromuscular junction is significantly increased in homozygous cdm164 and cdm164/Df(3R)DG2 animals compared to controls.
