This family consists of cyclin-dependent kinase inhibitor 3 or kinase associated phosphatase proteins from several mammalian species. The cyclin-dependent kinase (Cdk)-associated protein phosphatase (KAP) is a human dual specificity protein phosphatase that dephosphorylates Cdk2 on threonine 160 in a cyclin-dependent manner [1,2].
