Intrinsically disordered proteins have properties that are distinct from classical structured proteins
A. Are characterized by sequences rich in certain polar and charged amino acids (Gln, Ser, Pro, Glu, Lys, Gly, and Ala)
B. Ordered proteins tend to participate in signaling and regulation, whereas Intrinsically disordered proteins are involved largely in catalytic reactions, transport processes, and structural functions.
C. Nearly half of all prokaryotic proteins contain long disordered segments, whereas only a few percent of eukaryotic proteins do.
D. Often adopt a specific secondary or tertiary structure when they bind to other molecules such as ions, organic molecules, proteins, and nucleic acids.
