I'm looking for an actualized gene list of the MAPK signaling pathway (and other signaling cascades, too). I have microarray data, which I want to narrow to specific signaling cascades before I go to a gene ontology analysis. Does somebody know were can I get such a list? I tried to look at Reactome, but it is too branched in subpathways for my purposes. I also found the "GeneAssist Pathway Atlas", but I would like to have a more "independent" source. Thanks!
