A database of predicted and validated miRNA binding sites and correlated SNPs in human genome. dbSMR has a user-friendly interface where the information can be queried using either the gene name, microRNA name, polymorphism ID or transcript ID. Combination queries using ‘AND’ or ‘OR’ is also possible along with specifying the degree of change of intramolecular bonding with and without the polymorphism. Such a resource would enable researchers address questions like the role of regulatory SNPs in the 3′ UTRs and population specific regulatory modulations in the context of microRNA targets.
