Overexpression of cpxScer\UAS.cXa using Scer\GAL4elav-C155 or Scer\GAL4n-syb.PS decreases miniature excitatory junction potential (mEJP) frequency without affecting mEJP amplitude, but has no effect on evoked EJPs at the larval neuromuscular junction.
Expression of cpxScer\UAS.cXa using Scer\GAL4elav-C155 rescues the lethality and sterility of cpxSH1 mutants.
Expression of cpxScer\UAS.cXa rescues the decreased evoked excitatory junction potentials (EJPs) and the increased spontaneous EJPs in cpxSH1 mutants.
