Cryo-em structure of utp-bound p2y purinoceptor 4-minigq-nb35 complex
Structure:
Guanine nucleotide-binding protein g(s) subunit alpha isoforms short. Chain: a. Synonym: adenylate cyclase-stimulating g alpha protein. Engineered: yes. Other_details: 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(i)/g(s)/g(t) subunit
