This unconventional topology prevents glycosylation of M and plays a critical role in recruiting S and E proteins. Importantly, this is evolutionarily conserved among other beta-coronaviruses.
For example, the mathematical study of symmetry, or representation theory, is used in some of the models capable of predicting how proteins fold and twist into their three-dimensional shapes ...
Meanwhile, the topology of the E protein for the less virulent human coronaviruses is unknown. No evidence shows if it adopts a topology similar to the more virulent coronaviruses.
