The old version of RNABindR (cited in Terribilini et al. 2007) is no longer maintained. RNABindRPlus predicts RNA-binding residues from protein sequences by combining the output of an optimized SVM classifier with the output from a Homology-based method.
To first predict whether your query protein binds to RNA or not, you can use RNApred (Kumar et al. 2011) or DRNA (Zhao et al. 2010).
If you have a list of structure files for which you would like to calculate interface residues, please visit PRIDB.
