There are several major approaches to protein structure prediction.

The simplest and most reliable approach is

homology modeling, aligns the sequence of interest with the sequence of a homologous protein or domain of known structure—compensating for amino acid substitutions, insertions, and deletions—through modeling and energy minimization calculations.

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.
