摘要:

The G protein coupled receptor(GPCR), one of the members in the superfamily, which consists of thousands of integral membrane proteins, exerts a wide variety of physiological functions and responses to a large portion of the drug targets. The 3D structure of somatostatin receptor 1(SSTR1) was modeled and refined by means of homology modeling and molecular dynamics simulation. This model was assessed by Verify-3D and Vadar, which confirmed the reliability of the refined model. The interaction between the inhibitor cysteamine, somatostatin(SST) and SSTR1 was investigated by a molecular docking program, Affinity. The binding module not only showed the crucial residues involved in the interaction, but also provided important information about the interaction between SSTR1 on the one hand and ligands on the other, which might be the significant evidence for the structure-based design.
