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]

Cyclin E is a member of the cyclin family.

Cyclin-dependent kinase 2, also known as cell division protein kinase 2, or Cdk2, is an enzyme that in humans is encoded by the CDK2 gene. The protein encoded by this gene is a member of the cyclin-dependent kinase family of Ser/Thr protein kinases. This protein kinase is highly similar to the gene products of S. cerevisiae cdc28, and S. pombe cdc2, also known as Cdk1 in humans. It is a catalytic subunit of the cyclin-dependent kinase complex, whose activity is restricted to the G1-S phase of the cell cycle, where cells make proteins necessary for mitosis and replicate their DNA. This protein associates with and is regulated by the regulatory subunits of the complex including cyclin E or A. Cyclin E binds G1 phase Cdk2, which is required for the transition from G1 to S phase while binding with Cyclin A is required to progress through the S phase. Its activity is also regulated by phosphorylation. Multiple alternatively spliced variants and multiple transcription initiation sites of this gene have been reported. The role of this protein in G1-S transition has been recently questioned as cells lacking Cdk2 are reported to have no problem during this transition.

The CIP/KIP family is one of two families of mammalian cyclin dependent kinase (CDK) inhibitors (CKIs) involved in regulating the cell cycle. The CIP/KIP family is made up of three proteins: p21^cip1/waf1, P27^kip1, p57^kip2 These proteins share sequence homology at the N-terminal domain which allows them to bind to both the cyclin and CDK. Their activity primarily involves the binding and inhibition of G1/S- and S-Cdks; however, they have also been shown to play an important role in activating the G1-CDKs CDK4 and CDK6. In addition, more recent work has shown that CIP/KIP family members have a number of CDK-independent roles involving regulation of transcription, apoptosis, and the cytoskeleton.
