Fig. 7. Model of Drosophila myoblast fusion. Updated model of
myoblast fusion based on the known fusion genes following this work. Those
proteins that colocalize with the F-actin foci are colored yellow, those that
do not are purple. The localization of Rac partially overlaps with actin foci.
Solid arrows between proteins indicate well-established biochemical
interactions, while dashed arrows indicate genetic and/or suggested, but
unsubstantiated, biochemical interactions. See Discussion for details.
