New tool provides maps of protein interactions for 2,800 diseases
Scientists working in the Structural Bioinformatics and Network Biology Lab have included the more than 23,000 documented genetic mutations that affect the function of 2,000 proteins in an open-access web tool, and have positioned them on the map of known interactions between human proteins. dSysMap can be accessed free of charge at http://dsysmap.irbbarcelona.org, and scientists from around the world can add their data in an anonymous manner. Developed entirely at IRB Barcelona, dSysMap (“Disease-mutations Systemic Mapping”) provides molecular details about how mutations in certain proteins alter interactions with other proteins, thus affecting the correct funcion of cellular processes. The tool has explained, for example, why mutations in a single protein can cause two distinct diseases or why mutations in different proteins can trigger the same condition. …
