      Sphingomyelin synthase (SMS) has been noticed in recent years as a potential drug target. We have combined homolgy modeling, molecular docking and molecular dynamics simulation to derive a three-dimensional structural model of human sphingomyelin synthase 1 (hSMS1) in complex with sphingomyelin. This model can explain the possible catalytic mechanism of hSMS1, the high selectivity of hSMS1 towards phosphocholine and sphingomyelin as well as some other known experimental results. This model provides a reasonable structural basis for the discovery of novel small-molecule inhibitors of hSMS1 in the future.
