In Oryza sativa (rice) there are seven members in the NRAMP (natural resistance- associated macrophage protein) family of transporter proteins. They have been identified as OsNRAMP1, OsNRAMP2, OsNRAMP3, OsNRAMP4, OsNRAMP5, OsNRAMP6 and OsNRAMP7. Several metal ions like Zn2+, Mn2+, Fe2+, Cd2+ etc. have been studied to be transported via NRAMP transporter proteins in rice plant. In spite of this, very little information is available regarding these transporters. Hence it is important to computationally predict and characterize the OsNRAMP family of transporters for studying and understanding their molecular insights in future studies. For this purpose, various in silico methods and tools were used for the characterization of OsNRAMP family of transporter proteins. Physico-chemical properties of the protein sequences were calculated, putative transmembrane domains (TMDs) and conserved motif signatures were determined and their interaction partners were predicted. 3D models of all the members of OsNRAMP transporters were generated using online structure prediction tool followed by their analysis. In silico microarray analysis was done to understand the expression pattern of these transporters in rice plant. Currently, only limited knowledge is available about the structural and functional aspects of these transporters, hence this study would provide more theoretical information about them.
