Homology modeling and structural analysis of human P-glycoprotein.

ABSTRACT:

Unlabelled

Homology modeling and structural analysis of human P-glycoprotein (hP-gp) were performed with a software package the Molecular Operating Environment (MOE). A mouse P-gp (mP-gp; PDB code: 3G5U) was selected as a template for the 3D structure modeling of hP-gp. The modeled hP-gp showed significant 3D similarities at the drug biding site (DBS) to the mP-gp structure. The contact energy profiles of the hP-gp model were in good agreement with those of the mP-gp structure. Ramachandran plots revealed that only 3.5% of the amino acid residues were in the disfavored region for hP-gp. Further, docking simulations between 6-(methylsulfinyl)hexyl isothiocyanate (6-MITC) and the P-gp models revealed the similarity of the ligand-receptor bound location between the hP-gp and mP-gp mod
