Class vs. instance representation example

How a protein is described as an instance in RDF (according to the structure defined in an OWL ontology): (10 lines)

  Apoptosis-mediating surface antigen FAS FAS TNFRSF6 APT1 FAS1  My favorite protein

The same example protein described as a class in OWL. Not that is is extremely verbose compared to the above RDF. (88 lines)
