P{EPgy2}trsnEY06981 is inserted 716bp downstream of the start codon in exon 5.
Insertion in the 3' exon.
Under 12:12 light:dark zeitgeber cycles, trsnEY06981 homozygous mutants present increased average sleep time and decreased waking activity upon starvation conditions but not under normal diet conditions, as compared to wild-type controls; trsnEY06981 homozygous mutants do not show the starvation-induced sleep deprivation and increased waking activity observed in wild-type controls.
Homozygotes are viable and show no obvious morphological defects.
Homozygotes show normal geotatic, phototactic and olfactory response behaviours. However, homozygotes do show a significantly reduced benzaldehyde-induced jump response, demonstrating reduced motor activity.
Male and female fertility is normal in trsnEY06981 homozygotes.
