== Function ==
[https://www.uniprot.org/uniprot/ADCY5_CANLF ADCY5_CANLF] Catalyzes the formation of the signaling molecule cAMP in response to G-protein signaling (PubMed:1618857, PubMed:8428899, PubMed:10427002, PubMed:11087399, PubMed:15591060, PubMed:16766715, PubMed:19243146). Mediates signaling downstream of ADRB1. Regulates the increase of free cytosolic Ca(2+) in response to increased blood glucose levels and contributes to the regulation of Ca(2+)-dependent insulin secretion (By similarity).[UniProtKB:O95622]<ref>PMID:10427002</ref> <ref>PMID:11087399</ref> <ref>PMID:15591060</ref> <ref>PMID:1618857</ref> <ref>PMID:16766715</ref> <ref>PMID:19243146</ref> <ref>PMID:8428899</ref>   Lacks catalytic activity by itself, but can associate with isoform 1 to form active adenylyl cyclase.<ref>PMID:8428899</ref>

== Publication Abstract from PubMed ==
The crystal structure of a soluble, catalytically active form of adenylyl cyclase in a complex with its stimulatory heterotrimeric G protein alpha subunit (Gsalpha) and forskolin was determined to a resolution of 2.3 angstroms. When P-site inhibitors were soaked into native crystals of the complex, the active site of adenylyl cyclase was located and structural elements important for substrate recognition and catalysis were identified. On the basis of these and other structures, a molecular mechanism is proposed for the activation of adenylyl cyclase by Gsalpha.
