Triadin/Junctin Double Null Mouse Reveals a Differential Role for Triadin and Junctin in Anchoring CASQ to the jSR and Regulating Ca2+ Homeostasis
Figure 4
Sections at right angle to triads in sternomastoid (top row) and soleus (bottom row) muscles illustrating changes in dimensions of the jSR cisternae relative to WT.
Compare with Table 1. C and D) In Jct-null muscles the triads are slightly smaller than WT in sternomastoid (A), but somewhat larger in soleus (compare B and D; E and F) in Tdn-null fibers the jSR cisternae are smaller in all muscles; G and H) in the double null the dimensions are further reduced.
