An example of the estimation of gene functions using COXPRESdb. The thin red circles in (A), (B) and (C) indicate the link to the next step indicated by green arrows. (A) Top page. (B) Keyword search result. (C) Gene page for ACTR3. In the functional annotation section, the ‘list’ is linked to the list of genes, including the GO term and all GO subcategory terms. The ‘network’ is linked to GO network page (see Figure 2C). When a GO annotation is linked to any publication, the GO evidence codes (TAS and IPI in this example) of the GO annotation is linked to a corresponding PubMed page. The ‘ortholog page’ is linked to the page for parallel view of the gene page for this gene and its mouse ortholog. Small icons on the right side of the page are external links. Subcellular localizations are predicted by WoLF PSORT software, the score for which is scaled from 0 (less reliable) to 10 (most reliable), in integers. In the coexpression section, a coexpression network for the 20 highest coexpressed genes to the query gene is provided. The network consists of nodes and edges. Each node represents a coexpressed gene, which works as a link to the corresponding gene page, and each edge indicates the strength of coexpression by its thickness (see DATA SOURCES AND CALCULATIONS for details). The shaded node highlights the current gene, and the red edges, if any, indicate existence of reported PPIs according to the HPRD annotation (14). The orange edges indicate the existence of strong coexpression between the corresponding orthologs in mouse. The gene list is located in a table next to the network. The value of each expression pattern similarity (ExSim) in the table is highlighted by red colour corresponding to the edge thicknesses. The ‘detail’ in the table is linked to the coexpression viewer, which illustrates the contribution of each sample to the expression pattern similarity. See the text for the explanation of the other section shown. (D) Tissue-specific network page for neutrophils. ACTR3 is marked with a yellow symbol.
