About 75% of the charged residues in proteins are members of ion pairs that are located mostly on the protein surface.
Despite the strong electrostatic attraction interactions contribute little to the stability of a native protein.

Intrinsically disordered proteins lack a hydrophobic core, and have high densities of charged amino acid residues such as Lys, Arg, and Glu. Pro residues are also prominent, as they tend to disrupt ordered structures.

The lack of an ordered structure can facilitate a kind of functional promiscuity, allowing one protein to interact with multiple partners. Some intrinsically disordered proteins act to inhibit the action of other proteins by an unusual mechanism: wrapping around their protein targets.

The protein p27 is intrinsically disordered. It wraps around and inhibits the action of several enzymes called protein kinases that facilitate cell division.
