Yes! And I'd also add that there are others that come into play...

* Elucidating function by identifying similarity to other known structures

* Finding novel signaling mechanisms (see work on PHinder)

* Modeling co-receptor/ligand dynamics

* Identifying function of orphan receptors

* Working with ancestral genes by identifying descendant structure

* Classifying and clustering proteins based on solved structure

* Learning new biochemical mechanisms through active vs inactive state structures
