| 英文摘要 | The neuregulin/erbb system is a growth factor/receptor cascade that has been proven to be essential in the development of the heart and the sympathetic nervous system. however, the basis of the specificity of ligand-receptor recognition remains to be elucidated. in this study, the structures of nrg-1 beta/erbb3 and nrg-1 beta/erbb4 complexes were modeled based on the available structures of the homologous proteins. the binding free energies of nrg-1 beta to erbb3 and erbb4 were calculated using the molecular mechanics poisson-boltzmann surface area (mm-pbsa) computational method. in addition, computational alanine-scanning mutagenesis was performed in the binding site of nrg-1 beta and the difference in the binding free energies between nrg-1 beta mutants and the receptors was calculated. the results specify the contribution of each residue at the interaction interfaces to the binding affinity of nrg-1 beta with erbb3 and erbb4, identifying several important interaction residue pairs that are in agreement with previously acquired experimental data. this indicates that the presented structural models of nrg-1 beta/erbb3 and nrg-1 beta/erbb4 complexes are reliable and could be used to guide future studies, such as performing desirable mutations on nrg-1 beta to increase the binding affinity and selectivity to the receptor and discovering new therapeutic agents for the treatment of heart failure.
