Adherens junction signaling. (A) Epithelial adherens junction signaling. MS-identified phosphoproteins are shown in gray, and those for which significantly regulated phosphosites were measured are indicated with an orange border. Each P indicates a distinct regulated phosphosites, and the color is the same as that of the cluster it belongs to, according to Figure 2A. (B) Detailed list of the phosphosites depicted in (A). The reported amino acid position refers to the protein within the protein group for which a reference number (referred to as UniProtKB) was found in PhosphoSitePlus database. Bold, functional phosphosite (according to PhosphoSitePlus); ^, a redundant site.
