- Computational analysis of novel drug opportunities (CANDO) platform
The CANDO platform is comprised of a unique computational
multitarget fragment-based docking with dynamics protocol to
implement a comprehensive and efficient drug discovery pipeline with
higher efficiency, lowered cost, and increased success rates,
compared to current approaches. The pipeline is being applied to
evaluate how all FDA approved drugs, phenethylamines, tryptamines
and other physchoactive drugs bind to all known protein structures
in Homo sapiens and several pathogenic species. The binding
studies are combined with pharmacological, physiological, and
cheminformatics data to predict new therapeutics through repurposing
drugs already approved for other indications. The top predictions
are verified in the laboratory and clinic by our collaborators. The
project, funded by a 2010 NIH Director's
Pioneer Award, represents an integration of our group's applied
research on therapeutic discovery, building upon basic protein
structure, function, and interaction prediction research.
- Protinfo structure, function, and interaction prediction web server modules
The web server consists of modules to predict the protein structure
of individual molecules and complexes (ABCM, PPC), integrate limited
or noisy experimental data with our structure prediction algorithms
(PsiCSI, NMR), score protein structure decoys (SCORE), assign
proteins to particular functional categories and predict
functionally important residues (MFS, FSSA); predict protein ion
binding sites, types, affinities, and specificities from structure
(SOAK); and predict HIV-1 drug resistance/susceptibility (PIRSPred).
Currently structure, function, and interaction predictions for up to
100 molecules/day are performed.
- The Bioverse framework
The Bioverse provides a framework for exploring the relationships
among the molecular, genomic, proteomic, systems, and organismal
worlds. Our goal is to perform sophisticated analyses and
predictions based on genomic sequence data to annotate and
understand the interaction of protein sequence, structure, and
function, both at the single molecule as well as at the systems
levels. The Bioverse currently consists of more than 50 organismal
proteomes and is used by several hundred visitors accessing more
than 1,000 molecules/day. The current Bioverse 2D is being expanded
- ``Nutritious Rice for the World'' project
This project was developed in collaboration with IBM to predict the
structures, functions, and interactions of the rice interactome. More
over 200 media outlets have provided coverage on this project.
