Find Mice Using the International Mouse Strain Resource (IMSR)
Mouse lines carrying:
Fbxl3tm1Kei mutation (1 available); any Fbxl3 mutation (43 available)
♀ phenotype observed in females
♂ phenotype observed in males
N normal phenotype
behavior/neurological
prolonged circadian behavior period ( J:196293 )
• when mice are kept in constant darkness, free-running period is increased compared to in wild-type mice
abnormal circardian behavior entrainment ( J:196293 )
• when mice are entrained to a 12L:12D cycle (LD), the onset of active phase is delayed from the light-to-dark transition compared to in wild-type mice
• when transferred from constant darkness (DD) to LD, mice fail to entrain and free run as in DD
