Fig. 1: Thick filament structure in the relaxed cardiac sarcomere.
From: Structure of the native myosin filament in the relaxed cardiac sarcomere
a, Tomographic slice of a cardiac sarcomere, centred on the M band, depicting thick and thin filaments. Scale bar, 50 nm. b, Reconstructed thick and thin filaments mapped into a tomogram. Thin filaments obstructing the view on the thick filament were removed for clarity. Scale bar, 50 nm c, Structure of the thick filament from the M band to the C zone. For clarity, only the first four cMyBP-C stripes are shown. d, Illustration of the various sarcomere components and their colour code, which is maintained throughout the manuscript, unless otherwise indicated. For abbreviations and colour codes for the structural elements of the thick filament, see Extended Data Fig. 2k.
