Figure 6: Dnm1 self-assembles into large rings: Dnm1 assembles into large spirals, 100 nm in diameter compared to the 50 nm dynamin spirals (figure 6) (Ingerman et al., 2005,). The large Dnm1 spirals remarkably resemble mitochondria constriction sites observed in yeast. These results suggest that the structural properties of dynamin family members are uniquely tailored to fit their function. In addition, the binding of Dnm1 to its partner Mdv1 depends on the assembly state of Dnm1: Mdv1 readily binds Dnm1 in the spiral state only (Naylor et al., 2005)
