Abstract
The MIR algorithm provides an ab initio prediction of a proteins core residues. An improved version, the MIR2, is presented and validated on 3203 proteins from PDB. Structures are decomposed in Closed Loops, their limits constituting the observed core residues. They are predicted by MIR2 with an accuracy approaching 80%.
