Along with titin, one component of these protein complexes is bound by troponin and nebulin, while the other is comprised of coiled-coils and two head domains.
One protein in these structures has Ig domains which unfold one by one. Along with titin, one component of these protein complexes is bound by troponin and nebulin, while the other is comprised of coiled-coils and two head domains. They contain lighter H-bands and darker Z-discs and M-lines, which contribute to their characteristic coloration pattern. Containing thin and thick filaments made of actin and myosin, a bunch of them together make a myofibril. For 10 points, name this basic functional unit of striated muscle.
