CDK4-CCND3

简介
CDK4 protein, acting as a Ser/Thr kinase in the cyclin D-CDK4 complex, critically regulates the G(1)/S transition by phosphorylating and inhibiting RB family members. This activity, specifically hypophosphorylation of RB1 during early G(1) phase, releases E2F and promotes transcription of genes that drive G(1) progression. CDK4-CCND3 Protein, Human (sf9, GST, His) is the recombinant human-derived CDK4-CCND3, expressed by Sf9 insect cells, with N-His, N-GST labeled tag.

Protein Description
CDK4 (Cyclin-Dependent Kinase 4) and CCND3 (Cyclin D3) are crucial components of the cell cycle regulation machinery, playing significant roles in the transition from the G1 phase to the S phase of the cell cycle. Aberrations in this regulatory pathway are associated with various cancers, making it a focus of intense research. The CDK4-CCND3 complex is integral in promoting cell proliferation, and understanding its structure and function could provide insights into tumorigenesis and potential therapeutic targets. Researchers have developed recombinant proteins of CDK4 and CCND3 to study their interactions, enzymatic activity, and regulatory mechanisms in detail. These studies often utilize techniques such as X-ray crystallography and high-performance affinity chromatography to explore the conformational dynamics and binding affinities of the complex. Furthermore, exploring the specific roles of post-translational modifications on these proteins can unveil how they contribute to cancer progression. Investigating CDK4-CCND3 interactions also holds promise for developing CDK inhibitors as targeted cancer therapies, as these compounds could effectively disrupt aberrant cell cycle progression seen in malignancies. Overall, the characterization of CDK4-CCND3 recombinant proteins is pivotal for uncovering novel insights into cell cycle regulation and cancer therapeutics.
