Fig. 7

Dependence of membrane protein diffusion coefficients on temperature. Diffusion coefficients of selected mVenus fusion proteins were plotted against their molecular weight (a) and the number of transmembrane domains (TMs) (b). The data is fitted in a to a linear relation (for comparison) and in b to the Saffmann–Delbrück model. Dotted blue lines, dashed green lines, and dash-dotted red lines refer to 23 °C, 37 °C, and 43 °C, respectively. Inset in b shows the relative decrease of membrane viscosity as a function of temperature
