181_subcellular_locations_that_are_membranes

subcellular location
membrane
hierarchy

Find every subcellular location that is itself a kind of membrane, by reasoning back to locations:162 ("Membrane") over the same mixed rdfs:subClassOf/up:partOf hierarchy as #180. Nothing states directly that e.g. Endosome membrane "is a membrane" - it has to be derived by following the location hierarchy up to the Membrane term
