D-type cyclins use the A2' helix to dock the retinoblastoma protein Rb, and mutating cyclin D’s unique A2' helix interface slows proliferation.
- Why it matters: Cyclin D’s hydrophobic patch is already occupied by p21 and p27, raising how cyclin D can still engage its substrates during cell division.
- What they did: The study mapped how cyclin D docks Rb via its A2' helix and tested the effect of mutating the specific A2' helix interface on cell proliferation.
- The result: The work identifies a cyclin D–Rb docking mechanism that can be targeted by novel cancer therapeutics.
