WebAlso known as GPCRs. G-protein coupled receptors are only found in eukaryotes and they comprise of the largest known class of membrane receptors. In fact humans have more than 1,000 known different types of GPCRs, and each one is specific to a particular function. WebFeb 1, 2024 · Gαs-coupled GPCRs stimulate adenylyl cyclase, which converts ATP into cAMP, whereas Gαi-coupled GPCRs inhibit the production of cAMP by blocking adenylyl cyclases (AC). cAMP activates protein kinase A (PKA), which modulates transcription factors e.g. CREB (Figure 1 a).
