Catching up on some reading I came across a new database topic this week–MatrixDB. The goal of MatrixDB is to capture information about interactions involving extracellular molecules. I have always been a fan of extracellular matrix, but thought it was a pretty murky topic. I like the idea of a database devoted to this type of data.
There are entries for a given gene with details, of course. But there are also options to launch Cytoscape for building your own interactomes with the data.
MatrixDB can be found here: http://matrixdb.ibcp.fr/
I came across the paper about it here: http://www.ncbi.nlm.nih.gov/pubmed/19147664
MatrixDB, a database focused on extracellular protein-protein and protein-carbohydrate interactions. Chautard E, Ballut L, Thierry-Mieg N, Ricard-Blum S. Bioinformatics. 2009 Jan 28.
