Cryo-EM structure of ATP-bound P2Y purinoceptor 2-miniGq-Nb35 complex

Structural insight into the self-activation and G-protein coupling of P2Y2 receptor.

The N-terminal sequence of Gi1 is incorporated into the mini-G protein;Certain residues mutated to match Guanine nucleotide-binding protein G(q) subunit
Guanine nucleotide-binding protein G(s) subunit alpha isoforms short

Guanine nucleotide-binding protein G(I)/G(S)/G(T) subunit beta-1

Guanine nucleotide-binding protein G(I)/G(S)/G(O) subunit gamma-2

Adenylate cyclase-stimulating G alpha protein
