3. Figure 1
Development of Cis-regPred, a Tool to Identify Disordered CREs
(A) Mechanism of cis regulation of protein function; here autoinhibition. A CRE binds to a functional domain in cis and inhibits its function. Autoinhibition can be released or reinforced by multiple mechanisms.
(B) Feature score assignment. Shown are some scores for a window of size 5 centered on the amino acid Thr. Some scores are position-specific (e.g., disorder propensity), and some are averages of all properties within the window (e.g., number of phosphorylation sites) or the entire protein (e.g., protein globularity).
(C) Search for optimal MLR model parameters. Different window sizes and feature numbers were tested to find the combination that provided the highest AUC. The different AUCs that were calculated are provided here as a function of window size and feature number. (Inlay) AUC of training datasets (a), cross-validation sets (b), and test datasets (c) as a function of increasing feature numbers for a window size of 15. See also Figure S1 for details.
(D) Cis-regPred evaluation. ROC curves calculated for the test datasets.

4. Figure 2 Prediction Profiles of Test Proteins
Prediction profiles of two autoinhibited proteins (Plk4 and CAMKK2) that contain a CRE, and two non-autoinhibited proteins (Las17 and WASF1) that contain no CREs. More prediction profiles are shown in Figure S2.

5. Figure 3 Enrichment Analyses
(A) Enrichment of proteins with disordered CREs in different KEGG pathways. Shown is the significance (p values) of the enrichment. For comparison, enrichments of SLiM-containing proteins in different KEGG pathways are also shown.
(B) Significance (p values) of the enrichment of disease-associated mutations within disordered CREs, within disordered SLiMs, and within all disordered segments of the same proteins.
(C) Significance (p values) of the enrichment of cancer-associated mutations within disordered CREs, within disordered SLiMs, and within all disordered segments of the same proteins.

6. Figure 4
Map of Known and Predicted CREs within Proteins of the MAP Kinase Signaling Pathway
Proteins with predicted disordered CREs are circled in magenta. Proteins with known disordered and structured CREs are green and blue, respectively. The known CREs in this figure have an inhibitory function. Nodes in this figure were adopted from the KEGG pathway and thus may represent one or more proteins. For instance, the AKT node includes three proteins (At1, Akt2, and Akt3). All these proteins have CREs, but some are structured, whereas some are disordered. In this case, the node is black. Detailed prediction results and known CRE information are summarized in Table 1.
