Users can perform two tasks: the first task (two proteins) for predicting interactions between two proteins and the second task (network) for predicting interactions in a network of proteins. To predict interactions between two proteins, users need to supply two PDB IDs. Optionally, users can specify the chains used in the predictions.
thanks suneel, but my concern is the interaction of protein with ribonucleotide...i want to know about such a server that can predict the protein -RNA interaction
Try RPISeq and depends on what you are looking for,you can predict other interactions through here https://omictools.com/protein-rna-interactions-category
