The existence of any proteins in any fungus is not an automatic solution for anything - even more energy has to be expended to find it, purify it, test it, and notice any benefit for anything. There are likely a billion such proteins in nature right now that will never be discovered as useful for anything. Targeted research is likely a shorter and less expensive route to "finding" breakthrough medicines, especially since technology evolves exponentially.
