♀ phenotype observed in females
♂ phenotype observed in males
N normal phenotype
nervous system
abnormal miniature excitatory postsynaptic currents ( J:158605 )
• mice exhibit decreased spontaneous release frequency of miniature excitatory postsynaptic current (mEPSC) compared with wild-type mice
• however, expression of Doc2b restores normal mEPSC frequency
decreased neurotransmitter release ( J:158605 )
• average spontaneous release frequency is decreased compared to in wild-type mice
