Details

Detailed Description

Homozygotes are viable and fertile. p21, the product of the Cdkn1a gene, belongs to a family of regulators, known as cyclin-dependent kinase inhibitors, which modulate progression through the cell cycle. Following serum restimulation, expression of p21 is superinducible by cycloheximide in wild-type but not in p53-deficient cells. p53 appears to play a critical role in p21 induction following DNA damage. p21 can be regulated independently of p53 during normal tissue development, following serum stimulation, and during cellular differentiation.

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. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
