CDK4 Inhibitor - A Highly Noticed Breast Cancer Treatment Drug

CDK4, or cyclin-dependent kinase 4, is a crucial protein involved in cell cycle regulation in the human body. It plays a significant role in controlling the progression of cells from the G1 phase to the S phase, where DNA replication occurs. CDK4 forms a complex with cyclin D, which activates its kinase activity. This activation leads to the phosphorylation of key proteins involved in cell cycle progression, allowing cells to transition from the resting phase to the active phase of cell division. Dysregulation of CDK4 activity has been associated with various diseases, including cancer, making it an important target for pharmaceutical interventions.
