    ..Together, our results demonstrate that PDGFRbeta and Abl kinases function redundantly to promote efficient uptake of this obligate intracellular parasite. ..

    ..RNAi mediated suppression of single components of the WAVE and the Arp2/3 complex in the wing further suggests that WAVE-dependent Arp2/3-mediated actin nucleation is important for the maintenance of stable integrin junctions. ..

    ..Our results reveal a key role for the WAVE and Arp2/3 complexes, as well as a higher degree of variation than previously appreciated in actin nucleation pathways activated during Rickettsia invasion...

    ..Furthermore, our analysis indicates that F-actin binding is absolutely required for coronin 1B to exert its effects on whole-cell motility and lamellipodial dynamics. ..

    ..This functionally supports the hypothesis that TSE represents a general repression mechanism which can be co-opted by new transposable elements to regulate their activity after a transfer to the D. melanogaster genome. ..

    ..The requirement for Arp2/3 in ring canals indicates that the polymerization of actin filaments at the ring canal plasma membrane is important for driving ring canal growth. ..

    ..By controlling the stability, localization, and function of SCAR, these proteins may help to ensure that Arp2/3 activation and the generation of actin-based protrusions remain strictly dependant on local GTPase signaling. ..

    ..Other conserved residues were used with experimental constraints to propose how residues on the subunits ARPC1, ARPC2, ARPC4 and ARPC5 might interact with the mother filament at branch junctions.
