There are three different types of myofilaments: thick, thin, and elastic filaments. Thick filaments consist primarily of the protein myosin. Each thick filament is approximately 15 nm in diameter, and each is made of several hundred molecules of myosin. A myosin molecule is shaped like a golf club, with a tail formed of two intertwined chains and a double globular head projecting from it at an angle.
In the muscle-type receptors, found at the neuromuscular junction, receptors are either the embryonic form, composed of Î± 1, Î² 1, Î³, and Î´ subunits in a 2:1:1:1 ratio, or the adult form composed of Î± 1, Î² 1, Î´, and Îµ subunits in a 2:1:1:1 ratio.icotinic receptors, with a molecular mass of 290 kDa, are made up of five subunits, arranged symmetrically around a central pore. Each subunit comprises four transmembrane domains with both the N-and C-terminus located extracellularly.
