An N-terminal Z-disc region and a C-terminal M-line region bind to the Z-line and M-line of the sarcomere, respectively, so that a single titin molecule spans half the length of a sarcomere. Titin also contains binding sites for muscle-associated proteins so it serves as an adhesion template for the assembly of contractile machinery in muscle ...
The IUPAC name for Titin. This is the largest known protein and so has the longest chemical name. Written in full, it contains 189,819 letters. [48] Periplanone B: Periplanone B A pheromone of the female American cockroach. Thebacon: Thebacon Dihydrocodeinone enol acetate, an opioid analgesic or antitussive. [citation needed]
It is composed of a globular head with both ATP and actin binding sites, and a long tail involved in its polymerization into myosin filaments. Elastic filaments are made up of a giant protein called titin and hold the thick filaments in place. The protein complex composed of actin and myosin is sometimes referred to as actomyosin.
The giant protein titin (connectin) extends from the Z-line of the sarcomere, where it binds to the thick filament (myosin) system, to the M-band, where it is thought to interact with the thick filaments. Titin (and its splice isoforms) is the biggest single highly elasticated protein found in nature.
The main proteins involved are myosin, actin, and titin. Myosin and actin are the contractile proteins and titin is an elastic protein. The myofilaments act together in muscle contraction, and in order of size are a thick one of mostly myosin, a thin one of mostly actin, and a very thin one of mostly titin. [1] [2]

The amino acid sequence of titin differs between species. Furthermore within humans there are several splice variants. Hence there is a large family of related but distinct protein sequences that can be called titin and hence are a large number of names that can be assigned to titin. Which is the correct name? All of them.
Myomesin is bound to myosin at its N-terminal. Obscurin connects the myomesin dimers and binds to the C-terminal of titin. It is thought that the myomesin-titin interaction is vital for the execution of the mechanical functions of the Ser/Thr kinase domain of titin. [2] Myomesin is a protein family found in the M-line of the sarcomere structure.
