Unique mechanical behavior of utrophin halves is maintained upon deletion of terminal domains. (a) Schematic of utrophin constructs lacking terminal domains and a 10-repeat construct spanning both N- and C-terminal halves. (b) Coomassie-stained gel of purified proteins (5ug) imaged on UVP GelDoc-It® Imaging System. (c) Circular dichroism melt curves of utrophin constructs measured at 1 °C intervals. Average melting temperatures ± standard deviation for Utr R1-10, R11-22,R1-22, and R6-15 are 45.7 ± 0.26 °C, 50.5 ± 0.3 °C, 47.0 ± 0.49 °C, and 45.4 ± 1.6, respectively. (df) Plots of probability distributions vs unfolding force of each unfolding event (N) for Utr R1-10 (d), Utr R11-22 (e), Utr R1-22 (f), and Utr R6-15 (g).
