PredictProtein is an Internet service for sequence analysis and the prediction of protein structure and function. Users submit protein sequences or alignments; PredictProtein returns multiple sequence alignments, PROSITE sequence motifs, low-complexity regions (SEG), nuclear localisation signals, regions lacking regular structure (NORS) and predictions of secondary structure, solvent accessibility, globular regions, transmembrane helices, coiled-coil regions, structural switch regions, disulfide-bonds, sub-cellular localization, and functional annotations.Upon request fold recognition by prediction-based threading, CHOP domain assignments, predictions of transmembrane strands and inter-residue contacts are also available. For all services, users can submit their query either by electronic mail, or interactively from World Wide Web.

ProDom is a protein domain family database constructed automatically by clustering homologous segments. The ProDom building procedure MKDOM2 is based on recursive PSI-BLAST searches [ALTS2]. The source protein sequences are non-fragmentary sequences derived from SWISS-PROT and TrEMBL databases.
