Figure 1.

Domain structure of predicted Dictyostelium RasGEFs. Predicted protein sequences of all complete RasGEFs predicted from the Dictyostelium genome were searched in the SMART 4.0 database [34]. Individual domains are labeled in the figure. Pink, segments of low compositional complexity determined by the SEG program. Green, potential coiled-coil regions determined by the Coils2 program. Blue bars, transmembrane segments as predicted by the TMHMM2 program.
