Titin is the largest known protein.
Its human variant consists of 34,350 amino acids, with the molecular weight of the mature "canonical" isoform of the protein being approximately 3,816,188.13 Da.
Its mouse homologue is even larger, comprising 35,213 amino acids with a MW of 3,906,487.6 Da.
It has a theoretical isoelectric point of 6.01.
If you are referring to the amino acid sequence or its IUPAC name, probably no one remember it since it is over thousand residues in length and not nearly as popular of a hobby as memorizing digits of pi.
However, if you look at it from a certain perspective, it's not that hard to memorize the complete chemical name of titin. You can look at the name below for your convenience:
The protein's empirical chemical formula is C169,719H270,466N45,688O52,238S911.
Let's break it down for further convenience:
C 169,719
H 270,466
N 45,688
O 52,238
S 911
