Figure 3. Advantages and functions mediated by IDRs.
(A) IDRs can link structured domains, where their flexibility permits the protein to adopt multiple conformations; linear motifs within IDRs mediate protein interactions; posttranslational modification of residues within IDRs permits encoding and decoding of information [106]. (B) IDRs in protein sequences can increase the efficiency of degradation by the proteasome, thereby regulating protein half-life [53].
