Figure 6.

Length-dependence of Ca²⁺-sensitivity is similar in the wild type (black) and mdm (gray) fiber bundles. (A) Soleus and (B) extensor digitorum longus (EDL). Ca²⁺ sensitivity relationships at sarcomere lengths of 2.4 (dashed lines) and 3.0 µm (solid lines) from wild type and mdm fiber bundles (top). Individual data points for each curve are shown below. The shift in Ca²⁺-sensitivity from 2.4 to 3.0 µm was similar between genotypes. Reproduced with permission from Hessel et al. [26]. Copyright 2019, The Company of Biologists Ltd.
