Figure 4. STAC1 and STAC2 display different degrees of colocalization with CaV1.1 and CaV1.2 in skeletal myotubes.

Figure 4

(A) Domain structures of STAC1, STAC2, and STAC3. (B) STAC1 fails to show triad targeting in dysgenic myotubes expressing CaV1.1, but co-clusters with the channel in about half of the myotubes expressing CaV1.2 (51.8 ± 4.2%, N = 4, n = 120). Color overlay: 4X of blue rectangle. Scale bars: 10 μm and 5 μm. (C) Only STAC3 co-clusters with CaV1.1, while the three STAC proteins display different degrees of co-clustering with CaV1.2 (mean ± s.e.; N = 4, n = 120).
