DRIPPREDProteins don't always look like the pictures shown on the covers of journals. Most proteins have one or more residues that cannot be pinned down by X-ray crystallography or NMR. These regions are often functionally important and shouldn't just be thought of as "junk" or "linker" polypeptides, particularly in eukaryotic proteins. The prediction of these disordered regions can be useful for structural biologists who may have difficulties expressing or crystallising proteins. For molecular biologists, predicted disordered regions may help in the dissection of functional domains by mutagenesis.
The predictor was ranked somewhere between 2nd and 4th in the CASP6 evaluation (group number 347), and self-assessment shows approximately equal performance to David Jones' DISOPRED (but is non-overlapping in terms of per-residue predictions). DRIP-PRED is available free of charge for protein-by-protein research purposes (no automated requests allowed).
