Figure 1.

Topology plots of the three α-helical membrane proteins used in the study to probe the practical relationship between the application of window functions and PRE-derived distances. C99 (left) is 99 residues in length and has been spin-labeled at T729C. DAGK (middle) is 121 residues in length and was spin-labeled at I82C, and KCNE1 (right) is 129 residues in length and spin-labeled at S64C. The spin-labeled sites are highlighted in yellow.
