Fig. 3.

A, hierarchical clustering was performed using the localization ratios (a) No/Nuc, (b) No/Cyto, and (c) Nuc/Cyto and represented as a tree. In each case, high ratios are shown in red, low ratios are in green, and a 1:1 ratio is in black. B, visualization of the spatial proteomics data by graphical representation, plotting the log base 2 nuclear/cytoplasmic ratio on the x axis and log base 2 nucleolar/cytoplasmic ratio on the y axis. C, the Sm proteins associated with the small nuclear RNP subunits of spliceosomes (blue), proteins associated with small nucleolar RNPs (snoRNPs; red), and protein subunits of the 26 S proteasome cluster (green) are shown as examples. PEP, posterior error probability.
