Protein flexibility ranges from simple hinge movements to functional disorder.
Around half of all human proteins contain apparently disordered regions with
little 3D or functional information, and many of these proteins are associated
with disease. Building on the evolutionary couplings approach previously
successful in predicting 3D states of ordered proteins and RNA, we developed a
method to predict the potential for ordered states for all apparently disordered
proteins with sufficiently rich evolutionary information. The approach is highly
accurate (79%) for residue interactions as tested in more than 60 known
disordered regions captured in a bound or specific condition. Assessing the
potential for structure of more than 1,000 apparently disordered regions of human
proteins reveals a continuum of structural order with at least 50% with clear
propensity for three- or two-dimensional states. Co-evolutionary constraints
reveal hitherto unseen structures of functional importance in apparently
disordered proteins.
