Abstract
ATTED-II (http://atted.jp) and COXPRESdb (http://coxpresdb.hgc.jp) are databases we constructed for gene coexpression in Arabidopsis and in mammals, respectively. These databases can be used to design a wide variety of experiments, including the prioritization of genes for functional identification or for studies of regulatory relationships. Although Pearson's correlation coefficient (PCC) is widely used as a coexpression measure, we applied mutual rank (MR) of PCC for ATTED-II (ver. 5.0 and later) and COXPRESdb (ver. 3.0 and later). We will present the following characteristics of MR. (i) High potential to predict gene function. (ii) Independence against genes and data sources. (iii) Potential to draw understandable gene network.
