Myosin assembly: the power of multiubiquitylation.
Ubiquitylation provides a means of targeting substrate proteins for degradation by the proteasome. Novel findings in C. elegans (Hoppe et al., 2004, this issue of Cell) establish that two ubiquitin-ligases team up to multiubiquitylate the myosin chaperone UNC-45, suggesting a novel link between regulated protein degradation and myosin assembly.
