(PS)2 Protein Structure Prediction Server performs automated homology modeling by combining PSI-BLAST, IMPALA, and T-Coffee for template selection and target-template alignment. The final three-dimensional (3D) structure is built using RAMP or MODELLER.
3D-footprint provides estimates of binding specificity for all protein-DNA complexes available at the Protein Data Bank. The web interface allows the user to: (i) browse DNA-binding proteins by keyword; (ii) find proteins that recognize a similar DNA motif and (iii) BLAST similar DNA-binding proteins, highlighting interface residues in the resulting alignments. Comparisons with expert-curated databases RegulonDB and TRANSFAC support the quality of structure-based estimates of specificity.
3Matrix is a tool for visualizing protein sequence motifs and their properties in 3 dimensions. This tool needs to be downloaded and run locally on your own machine.
AGenDA is a web tool that compares the genomic sequences from evolutionarily related organisms in order to make gene predictions. It takes pairs of genomic sequences as input, aligns the sequences, and makes predictions based on splice signals, start and stop codons, and areas of conserved sequence.
ALLGEN server provides various tools for multiple sequence alignments, clustering, and assembly of ESTs. It also includes search tools for transcription factor binding sites (TFBS), repeated patterns, and transposons.
The Alternative Splicing Gallery (ASG) takes an identifier such as an EnsEMBL gene ID or a RefSeq ID as input, and provides a graph mapping splice events to transcript information. The user can also view GO information for the record, and select one or more exons and download the resulting sequence. ASG also links out to other alternative splicing databases like ProSplicer.
This page contains various resources for comparative protein structure modelling and analysis from the Sali Lab at University of California at San Francisco (UCSF).
AREsite is an online resource for the detailed investigation of AU-rich elements (ARE) in vertebrate mRNA 3'-untranslated regions (UTRs). AREsite allows one to quantify the structuredness of ARE motif sites in terms of opening energies and accessibility probabilities. A detailed phylogenetic analysis of ARE motifs and incorporate information about experimentally validated targets of the ARE-binding proteins TTP, HuR and Auf1 is also provided.
DNA sequence viewer and annotation tool; allows visualization of sequence features and results of analyses within the context of the sequence and its 6-frame translation; available for UNIX, Windows and Macintosh.
