P{lacW}beP1 is inserted 21 bp 5' of the CG32594 transcriptional start site.
In beP1 homozygotes and beP1/beEY08069 adults, long-term memory resulting from Pavlovian olfactory learning tested 1 day after spaced training (10 training sessions with a 15 minute rest between each) is significantly impaired. However, no effect is seen on long term memory tested 1 day after massed training (10 training sessions with no intervals) or on the rate of memory loss after after a single training session.
Recordings from a neuro-muscular junction (muscle 12, segment 3 or 4) show that while the mean amplitude of spontaneous mini excitatory junction currents (EJCs) is normal in beP1/+ animals, the mean amplitude of evoked EJCs is significantly lower than normal (by nearly 35%), consistent with a drop in quantal content to ~65% of wild-type. The synaptic structure at neuro-muscular junctions appears to be normal in these animals.
Scamp[+]/ScampEP1593, beP1 has abnormal memory | recessive phenotype
In beP1/ScampEP1593 adults, long-term memory resulting from Pavlovian olfactory learning tested 1 day after spaced training (10 training sessions with a 15 minute rest between each) is significantly impaired. However, no effect is seen on long term memory tested 1 day after massed training (10 training sessions with no intervals) or on the rate of memory loss after after a single training session. This phenotype is not seen in beP1/+ or ScampEP1593/+ animals.

This phenotype is not seen in beP1/+ or ScampEP1593/+ animals.
