Cyclin-dependent kinases (CDKs) regulation in mammals is increasingly understood, with new functions discovered beyond cell cycle control. Further research is needed to apply crystallographic insights to diverse CDK complexes and their roles.

Area of Science:

  • Molecular Biology
  • Cell Biology
  • Biochemistry

Background:

  • Cyclin-dependent kinases (CDKs) are crucial regulators of the cell cycle in mammalian cells.
  • Understanding of CDK regulation has advanced significantly, revealing diverse enzymatic functions.
  • Crystallographic studies have elucidated the activation and inactivation mechanisms of a prototypic CDK-cyclin complex.

Purpose of the Study:

  • To extend the understanding of CDK-cyclin complex activation and inactivation beyond prototypic examples.
  • To investigate the roles of various CDKs in mammalian cell cycle progression.
  • To explore the expanding interest in CDK regulation beyond the traditional cell cycle field.

Main Methods:

  • Crystallographic studies
  • Biochemical assays
