p27Kip1 is one of the the inhibitor for a series of cyclin and cyclin-dependent kinase (CDK) complex which plays a central role in the regulation of cell cycle progression. p27Kip1-deficient mice display a variety of abnormalities such as increased body size with their enlarged organs and disorganized layer pattern in retina (Figure right). About half of mutants develop tumors originating from the intermediate lobe of pituitary gland by 12 weeks of age. This strain is useful for cell cycle research and tumor biology.
