More accurately: very early versions of the GO had a term named
"protein", but this was obsoleted because it was out of scope for the
GO. The term was obsoleted, but a historic record is maintained. GO
does not intend to say "protein is_a thing", what you are seeing is
probably an artefact of the translation of obsoletion metadata to OWL.
