Strain Information
Type Mutant Strain; Transgenic; Additional information on Genetically Engineered and Mutant Mice. Visit our online Nomenclature tutorial. Species laboratory mouse Donating Investigator Michael K Ahlijanian, Pfizer Central Research Description
These transgenic animals display a robust expression of the amino terminal proteolytic fragment p25 of human CDK5R1. Expression is detected in the amygdala, thalamus/hypothalamus, cerebral cortex, and cerebellum. The p25 fragment acts as a positive allosteric regulator of cyclin-dependent kinase 5 (Cdk5), a kinase known to phosphorylate the microtubule-binding protein tau. A two-fold increase in the catalytic activity of Cdk5 is observed in these mice. In contrast to wildtype control mice, brains from 4-month-old exhibit the presence of tau and neurofilament phosphoepitopes. Utlrastructurally, axonal swelling in neurons from the amygdala and spinal cord is observed. Affected neurons possess numerous, abnormally clustered mitochondria and lysosomes, with some evidence of cytoskeletal disorganization. Mice exhibit whole-body tremors at 4-9 weeks of age and enhanced open-field locomotor activity. Aspects of this phenotype are similar to Alzheimer's, Pick's and other neurodegenerative diseases.

The Jackson Laboratory's Genotype Promise
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.Ordering Information
