Description
To study the molecular mechanism by which nonmuscle myosin II (MII) regulates protrusion and adhesion dynamics in migrating cells, NIH3T3 cells were transfected with myc-tagged phosphomimetic constitutively active MLC mutants (MLCaa, green). After 20' exposure to PDGF, which induces myosin-inactivation, stress fiber disassembly, and stimulates fibroblast motility, the cells were fixed and co-stained for TRIO (a multifunctional, multidomain Rho guanine nucleotide exchange factor, red) and filamentous actin (blue). These findings help elucidate a functional link between MII and Rac1/Cdc42 GTPases, which may regulate protrusion/adhesion dynamics in migrating cells.
