JTT was the evolutionary substitution model applied. of models. As a result, the PTP1B or PTP non-receptor type 1 homologies show high conservativity where about 70% positions on main structures are conserved. Within PTP domain name (3C277), the most variable positions are 12, 13, 19 and 24 which is a part of the second aryl binding site. Moreover, there are important evolutional mutations that can switch the conformation of the proteins, for instance, hydrophilic N139 changed to hydrophobic Gly (mPTP1B); E132 to proline in the hydrophobic core structure or Y46 to cystein in pTyr acknowledgement loop. These variations/differences should be taken into account for rational inhibitor design and in choosing suitable animal models for drug screening and evaluation. Moreover, our study suggests critically potential models which are and in addition to the best one Among these models, the and are preferable over thanks to their similarity in binding affinity and binding modes to investigated PTP1B inhibitors.
