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.
includes: TRANSFAC - transcription factor database; Patho DB - mutated forms of transcription factors and binding sites that are pathologically relevant; S/MARt DB - scaffold matrix transaction database; TRANSPATH - gene regulatory pathway database.
The Blocks WWW server provides tools to search DNA and protein queries against the Blocks database of multiple alignments, which represent conserved protein regions.
A tool for the detection of conserved residue clusters from an input PDB file. Structural properties of each residue, such as solvent accessibility (ASA), secondary structure, conservation score etc. and the conserved residue clusters are also computed.
CONREAL (Conserved Regulatory Elements Anchored Alignment) allows identification of transcription factor binding sites (TFBS) that are conserved between two orthologous promoter sequences.
E-RNAi is a tool for designing and evaluating dsRNA constructs suitable for RNAi experiments in 12 organisms including Drosophila, C. elegans, human and other emerging model organisms. E-RNAi also facilitates the design of secondary RNAi reagents for validation experiments, evaluation of pooled siRNA reagents and batch design.
enoLOGOS creates sequence logos based on a variety of input, including sequence alignments, probability and alignment matrices and energy measurements.
Easy Sequencing in Postscript (ESPript) is a utility which provides postscript output for aligned sequences with graphical enhancements and structural information.
Identify Conserved targets of a Regulon (iCR) predicts regulatory binding sites based on conservation across multiple species. The user provides an ungapped multiple sequence alignment representing the regulatory binding site. iCR reports back with predicted binding sites that are conserved and highlights the downstream co-regulated genes.
Database of protein orthologs that interact (interologs) and proteins with conserved regulatory relationships across species (regulogs). Contains data for C. elegans, Drosophila, Arabidopsis, and Yeast.
Server designed to pinpoint protein-DNA interaction sites at the base pair level. Uses ChIP-array data, word enumeration and position-specific weight matrix updating to search for motifs representing these interaction sites.
