Fig. 6: Comparison of KAP/CKS1/CDC25A with GDSEID binding region of CDK2.

a Overlay of the trimeric complex (CDK2-Cyclin A in grey, CDC25A in green) with the CDK2-KAP crystal structure (PDB 1FQ1, KAP in blue) and (c) CDK2-CKS1 crystal structure (PDB 1BUH, CKS1 in orange). The CDK2 GDSEID sequence and αG helix are highlighted in yellow. b Ribbon diagram of the GDSEID region of CDK2 bound to CDC25A (green) and KAP (blue), which bind to opposing faces of the αG helix. d Ribbon diagram of the GDSEID region of CDK2 bound to CDC25A (green) and CKS1 (orange), showing an overlap in the binding region but differences in specific residue interactions.
