ES Cell line
Background strainC57BL/6NJcl
Strain developmentWe induced random point mutations by ethylnitrosourea (ENU) and screened for dominant sleep and wakefulness abnormalities. Through our screening, we established a mutant pedigree, which we termed Sleepy (Slp), with a markedly prolonged sleep time. Whole-exome sequencing 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 by using conventional knock-in in embryonic stem (ES) cells. Further examine these functions, we introduced a Flag-HA sequence into the Sik3Slp allele using CRISPR/Cas9 technology.
