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:

I came across the paper about it here:

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.
