T4 lysozyme was fused recombinantly at the C terminus of Cdk4, with a GS linker in between. This was done to verify placement of proteins in the complex. Therefore, the total mass of Cdk4-T4Lys is 51kDa rather that 33.7kDa for pure Cdk4.

Image stacks were dose weighted, drift corrected, binned to 1.22A/pix and summed using new UCSF DriftCorr program. The particles were picked and the CTF was estimated the same way as other maps in the series. Rounds of 2D classification (300 classes, 50 iterations) followed by 3D classification (2 classes, 50 iterations) in Relion 1.4 were used to eliminate low quality particles. Using the final set of particles, 3D Auto-refine feature in Relion 1.4 was used to generate the final maps.
