Overview
CDK4 encodes cyclin-dependent kinase 4, a serine/threonine kinase that forms a complex with D-type cyclins (CYCLIN D1, D2, D3) to drive cell cycle progression from G1 to S phase. CDK4 is a key regulator of the cell cycle and is frequently dysregulated in cancer. In the nervous system, CDK4 plays important roles in neurogenesis, synaptic plasticity, and cell cycle control. Aberrant CDK4 activation is implicated in neuronal death in neurodegenerative diseases [@cdk2007][@cell2013].
The study of Cdk4 Gene has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.

Cell Cycle Control
CDK4 in G1 Phase
CDK4 is the key G1 kinase:
[G1 progression*: Essential for G1/S transition](/genes/ran)
CDK4 links growth factor signaling to cell cycle progression. In the brain, dysregulated CDK4 activity contributes to neuronal dysfunction in AD and PD. CDK4/6 inhibitors approved for cancer may have therapeutic potential in neurodegeneration.
