Some virus like HRSV has the capability to segregate truncated forms of its proteins, like attachment G in this case https://academic.oup.com/intimm/article/20/9/1169/667012. I have some fasta sequence of some proteins, and I want to know if there is some tool I can use to predict the possibility of that proteins can be truncated without lost their functions, and if possible, predict if it can be segregated. Thank you.
