Appearance
Strain developmentWe induced random point mutations by ethylnitrosourea (ENU) and screened for dominant sleep and wakefulness abnormalities through EEG/EMG-based sleep staging. Through our screening, we established a mutant pedigree, which we termed Sleepy (Slp), with a markedly prolonged sleep time. Whole-exome sequencing of Sleepy mutants identified a heterozygous single nucleotide substitution at the splice donor site for intron 13 of the Sik3 gene. To confirm genetically that the Sik3 splice mutation is the sole cause of the long-sleep phenotype, we introduced the Sik3 exon 13-skipping allele into wild-type mice by using conventional knock-in in embryonic stem (ES) cells. As expected, these mouse lines exhibited markedly reduced wake time, similar to the original Sleepy pedigree.
Strain descriptionThis mouse line exhibited markedly reduced wake time.
