CDK2AP1
Cyclin-dependent kinase 2-associated protein 1 is an enzyme that in humans is encoded by the CDK2AP1 gene.[5][6][7]
Function
The protein encoded by this gene is a specific CDK2-associated protein, which is thought to negatively regulate CDK2 activity by sequestering monomeric CDK2, and targeting CDK2 for proteolysis. This protein was found to also interact with DNA polymerase alpha/primase and mediate the phosphorylation of the large p180 subunit, which suggested the regulatory role in DNA replication during S phase of the cell cycle. A similar gene in hamster was isolated from, and functions as a growth suppressor of normal keratinocytes.[7]
Interactions
CDK2AP1 has been shown to interact with Cyclin-dependent kinase 2.[8]
It interacts with unnamed protein product (BC006130) which may mediate inhibitory effect of CDK2AP1 on cell proliferation.[9]
