Just because it refers to a set of things does not mean I need to model it by an owl:Class. I can also have an owl:Class Population and an instance of it populationOfTheUS, which would be an instance, not an owl:Class, although it seems to correspond to a set of people. Similarly, a typical approach would be to have a class Protein and an instance EGFR ("a protein") that refers to a large number of molecules scattered all over the globe. The statements from UniProt, as I understand them, make perfect sense: there is a protein that has been isolated from that plant, and can also be found in fruit fly embryos. I don't have the knowledge to check whether it is true, but it seems to make sense to me.
