Researchers revealed protein kinase B/Akt conformational changes using fluorescence resonance energy transfer. This offers insights into the enzyme's behavior in mammalian signaling pathways.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Cell Signaling

Background:

  • Protein kinases are crucial enzymes regulating cellular processes.
  • Understanding protein kinase conformational changes is key to deciphering signaling pathways.
