NetFlow3D is a computational tool aiming at deciphering how somatic mutations function in cancer. It specifically focuses on protein-altering mutations. By combining the insights from protein structure and protein-protein interaction network, NetFlow3D nominates potential driver mutations and map their functional effects on multiple scales. NetFlow3D web server allows the users to (i) browse and download the results generated from TCGA pan-cancer data, and (ii) run NetFlow3D on their own data.

3D SARS-CoVID-2-Human Interactome:

To facilitate broader exploration of how pathogen–host interactions might impact transmission and virulence in the ongoing COVID-19 pandemic, we performed state-of-the-art interface prediction followed by molecular docking to construct a three-dimensional structural interactome between SARS-CoV-2 and human. We additionally carried out downstream meta-analyses to investigate enrichment of sequence divergence between SARS-CoV-1 and SARS-CoV-2 or human population variants along viral–human protein-interaction interfaces, predict changes in binding affinity by these mutations/variants and further prioritize drug repurposing candidates predicted to competitively bind human targets.

mutation3D is a functional prediction and visualization tool for studying the spatial arrangement of amino acid substitutions on protein models and structures. It can be used to identify clusters of amino acid substitutions arising from somatic cancer mutations across many patients in order to identify functional hotspots and fuel downstream hypotheses. It is also useful for clustering other kinds of mutational data, or simply as a tool to quickly assess relative locations of amino acids in proteins.

BISQUE: The BIological SeQUence Exchange

BISQUE is a bioinformatics tool enabling locus and variant-specific conversion among human gene, transcript, and protein identifiers from several popular databases. BISQUE implements a graph-traversal algorithm to allow conversion between any two database identifiers, including biologically downstream (gene -> transcript -> protein) and upstream conversions (protein -> transcript -> gene). All major functionality of BISQUE is available via this web interface, a URL-based web service, and a downloadable command-line tool, which includes a python module and deployable MySQL database.

HINT: High-quality INTeractomes

HINT is a curated compilation of high-quality protein-protein interactions from 8 interactome resources (BioGRID, MINT, iRefWeb, DIP, IntAct, HPRD, MIPS, and the PDB). Interactions are filtered both systematically and manually to remove erroneous and low-quality interactions, and is updated every night. HINT can be used for individual queries as well as for batch downloads.
HINT has been updated in August, 2021.

ClusterONEClustering with Overlapping Neighborhood Expansion:

ClusterONE is a graph clustering algorithm that is able to handle weighted graphs and readily generates overlapping clusters. Owing to these properties, it is especially useful for detecting protein complexes in protein-protein interaction networks with associated confidence values. ClusterONE is available as a standalone command-line application, or as a plugin to Cytoscape or ProCope.
ClusterONE is maintained by collaborators at the Paccanaro Lab.
