Titin is the third most abundant protein in muscle (after myosin and actin), and an adult human contains approximately 0.5 kg of titin. [13] With its length of ~27,000 to ~35,000 amino acids (depending on the splice isoform ), titin is the largest known protein . [ 14 ]
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 ...
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] MOM: A functional group often employed in organic synthesis to protect alcohols. Periplanone B: Periplanone B A pheromone of the female American cockroach. Thebacon
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 ...
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.
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]
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. What makes one arbitrarily chosen name so special? Adding the full name has ...
Alpha-actinin-2 is a 103.8 kDa protein composed of 894 amino acids. [6] [7] Each molecule is rod-shaped (35 nm in length) and it homodimerizes in an anti-parallel fashion.. Each monomer has an N-terminal actin-binding region composed of two calponin homology domains, two C-terminal EF hand domains, and four tandem spectrin-like repeats form the rod domain in the central region of the molecule.
