Cryo-EM of zebrafish cardiac thin filaments. A: An excised adult Zebrafish heart, letters (in yellow) show V-Ventricle, A-Atrium B-bulbus arteriosus. B: A typical negative stain EM micrograph of isolated thin filaments, visible troponin complexes indicated with white arrows. C: Cryo-EM image illustrating the periodic binding of troponin on the thin filament (green circles) at a spacing of ~ 385Å D: 2D class averages from cryo-EM data with pairs of troponin labelling the two strands of actin (green circles); tropomyosin strands are also visible (top and bottom images)
