These transgenic mice express full-length, wildtype human CSNK1D (casein kinase 1, delta), and may be useful in studies of circadian patterns. This is line 433, carrying 2-3 copies of the transgene.

Transgenic (Reporter, Inserted expressed sequence, Humanized sequence) |
Mutations in the human CSNK1D (casein kinase 1, delta) gene have been associated with symptoms of Familial Advanced Sleep Phase Syndrome (FASPS). Evidence suggests that this kinase interacts with PER2 (period circadian clock 2) binding domains to regulate circadian period.
Hemizygous transgenic mice express 2-3 copies of the full-length, wildtype human gene. Under 12 hour light-12 hour dark (LD) and constant darkness (DD)conditions, these mice and T44A transgenic mutant mice (see Stock No. 022148) show similar and robust circadian rhythms of wheel-running activity. Transgenic mice carrying this wildtype form of the human gene exhibit a circadian period of approximately 23.78 hours, but when placed in combination with a Per2 S662G mutation (e.g. Stock No. 013456 or Stock No. 013700), which shortens circadian time to 22 hrs, the wildtype CSNK1D transgene further shortens the circadian period to 20.8 hours.
No phenotypic differences have been observed between this strain and founder line 432 (see Stock No. 022149).
Human BAC RP11-1376P16, containing the entire CSNK1D gene on a 190-kb genomic insert (Genbank accession number AC129510) and a carboxy terminal internal ribosome entry site (IRES) followed by enhanced green fluorescent protein gene (EGFP) were introduced to C57BL/6 x SJL F1 embryos. Resultant mice were backcrossed to C57BL/6 for more than 10 generations by the donating laboratory. Fluorescence has not been directly detected in transgenic mice. This is line 433, carrying 2-3 copies of the transgene.

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
