Threading is a computational technique that attempts

to determine the unknown structure of a protein by ascertaining

whether it is consistent with a known protein structure.

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.
