Titin A-band has homologs in invertebrates, such as twitchin (unc-22) and projectin, which also contain Ig and FNIII repeats and a protein kinase domain. [30] The gene duplication events took place independently but were from the same ancestral Ig and FNIII domains. It is said that the protein titin was the first to diverge out of the family. [28]
The IUPAC nomenclature for organic chemical compounds is open-ended, giving rise to the 189,819-letter chemical name Methionylthreonyl threonyl . . . iso leucine for the protein also known as titin, which is involved in striated muscle formation. In nature, DNA molecules can be much bigger than protein molecules and therefore potentially be ...
Thick filaments consist primarily of the protein myosin, that is responsible for force generation. 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.
Even the smallest proteins contain no fewer than 20 amino acids, making for some pretty long names in their own right; titin, however, is the human body’s largest protein. Total amino acid count ...
Obscurin is a protein that in humans is encoded by the OBSCN gene. [5] [6] [7] Obscurin belongs to the family of giant sarcomeric signaling proteins that includes titin and nebulin. Obscurin is expressed in cardiac and skeletal muscle, and plays a role in the organization of myofibrils during sarcomere assembly.

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.
