Figure 4. Cellular and functional classification of Ubl targets.
(A) Enrichment analyses of “molecular functions” among Ubl targets, assessed by over-representation of Gene Ontology (GO) terms for the targets of each Ubl. Terms discussed in the text appear in red. (B) Same analysis as in (A) but for the “biological processes” annotations. (C) Detailed breakdown of the subset of kinases in the network, and their Ubl specificities (color-coded lines), showing an extensive crosstalk between kinases and different Ubl modifiers. See Figure S2A for a higher resolution of this image with protein names. See related figures S2 and S3.
