There is a new GPCR structure available, an engineered form of human A2a complexed with an agonist ligand, the Phase 2 clinical candidate UK-432,097 (PDBe:3QAK). The paper accompanying this structure is available on the Science website.

I've also updated the GPCR page with all the recent structures (there were some new beta-1 and beta-2 structures as well).
