Abstract: Heavy chain phosphorylation plays a central role in regulating myosin II bipolar filament assembly in Dictyostelium, as well as in higher eukaryotic nonmuscle cells. Our previous work has demonstrated that the WDrepeat domain of Dictyostelium myosin II heavy chain kinase B (MHCK-B), unlike its counterpart in MHCK-A, is not absolutely required for targeting of the kinase to phosphorylate MHC. Thus, we tested the hypothesis that an asparagine-rich and structurally disordered region that is unique to MHCK-B can by itself function in substrate targeting.
