Protein function

Motifs and chemistry dictate the role of intrinsically disordered regions

Research shows that the function of intrinsically disordered regions within proteins relies on both linear sequence motifs and broader chemical context, allowing evolution to preserve function without strict sequence conservation. Motifs and contextual chemistry jointly determine activity, with chemistry able to compensate for a loss of motifs.
