“…More information on these datasets is found in Ramírez et al (2007). In addition, several domain–domain interaction datasets are offered by DASMI servers: three experimental datasets derived from 3D structures obtained by X-ray crystallography or NMR spectroscopy [3did (Stein et al , 2009), iPfam (Finn et al , 2005) and PiNS (Bordner and Gorin, 2008)] and 11 predicted datasets (Chen and Liu, 2005; Guimarães et al , 2006; Jothi et al , 2006; Lee et al , 2006a; Liu et al , 2005; Ng et al , 2003; Pagel et al , 2008; Riley et al , 2005; Schelhorn et al , 2008; Wang et al , 2007; Wuchty, 2006), see Supplementary Data File 3. Moreover, we set up two confidence servers, FunSimMat (Schlicker and Albrecht, 2008; Schlicker et al , 2006) and Domain support (Finn et al , 2005; Ramírez et al , 2007), which can be used to assess the reliability of protein interactions.…”
