1BPV - PubMed Abstract: 
Titin is a huge protein ( approximately 3 MDa) that is present in the contractile unit (sarcomere) of striated muscle and has a key role in muscle assembly and elasticity. Titin is mainly composed of two types of module (type I and II). Type I modules are found exclusively in the region of titin localised in the A band, where they are arranged in a super-repeat pattern that correlates with the ultrastructure of the thick filament. No structure of a titin type I module has been reported so far.
