A phototaxis signalling complex in Dictyostelium discoideum

Phototaxis has been studied in a variety of organisms belonging to all three major taxonomic domains-the bacteria, the archaea and the eukarya. Dietyostelium discoideum is one of a small number of eukaryotic organisms which are amenable to studying the signalling pathways involved in phototaxis. In this study we provide evidence based on protein coimmunoprecipitation for a phototaxis signalling complex in Dictyostelium that includes the proteins RasD, filamin, ErkB, GRP125 and PKB.
