Titin is the largest known protein, consisting of 34,350 amino acids. It is considered by some as the largest word in the English language, with 189,819 letters. The molecular weight of the mature protein is approximately 2,993,442.763 Da, and it has a theoretical isoelectric point of 6.01 The protein’s empirical chemical formula is C132983H211861N36149O40883S693. It has a theoretical instability index (II) of 39.69, indicating that it would be stable in a test tube. The protein’s in vivo half-life, the time it takes for half of the amount of protein in a cell to disappear after its synthesis in the cell, is predicted to be approximately 30 hours (in mammalian reticulocytes).
