Figure 5.

Functional classes for nucleolar proteins identified in the two independent proteomic analyses of purified human nucleoli. Functional classes were deduced for the 213 nucleolar proteins identified in this study and listed in the supplemental table, online. (A) and for 262 nucleolar proteins identified in the study of Andersen et al. (2002) (B). The name of the class with its corresponding abbreviation used in the supplemental table (C1–C10) is given. The percentage of total proteins found within each class is indicated. In addition, for each class, the number of proteins with a demonstrated involvement in the biological process is given, followed by the number of proteins with hypothetical involvement in this biological process in italics.
