The protein kinase CK1 phosphorylates serine residues that are located close to another phosphoserine in the consensus pSer-Xaa-Xaa-Ser. This specificity generates regions in its target proteins containing two or more neighbouring phosphoserine residues, termed here multisite phosphorylation domains (MPDs). In
