Integrating chemistry and biology to provide the ChemiBiological profiles linking protein networks and small molecules with their toxicological and therapeutic outcomes, Protein Pathways was a bioinformatics company founded on the basis of novel proprietary algorithms for high-throughput analysis of genomes and proteomes. The firm computationally analyzes and maps protein-protein interactions -both licensing out its data and also using the information as a principal tool for drug development. Underlying protein function and interaction discovery efforts, Protein Pathways had aimed to identify novel and disease- related protein interactions, complexes, and pathways to accelerate the discovery of drug targets and protein pharmaceuticals. Principals of the firm arenow either retired or have joined academic institutions to engage in similar work
