Day 51 (2q31.1-2q32.1): titin, the largest protein


Day 51 has 42 genes (browser view), including TTN (titin). Titin gets its name by virtue of being the largest protein. It is a major component of muscle.

According to Wikipedia:

As the largest known protein, titin also has the longest IUPAC name of a protein. The full chemical name of the human canonical form of titin, which starts methionyl and ends isoleucine, contains 189,819 letters and is sometimes stated to be the longest word in the English language, or any language. However, lexicographers regard generic names of chemical compounds as verbal formulae rather than English words.
