This review discusses the occurrence of heteromers formed by different adenosine receptors in mammals, emphasizing the tetrameric structural arrangements and functional diversity they provide to adenosinergic signaling.
Adenosine is one of the most ancient signaling molecules and has receptors in both animals and plants. In mammals there are four specific receptors, A(1), A(2A), A(2B), and A(3), which belong to the superfamily of G-protein-coupled receptors (GPCRs). Evidence accumulated in the last 20 years indicates that GPCRs are often expressed as oligomeric complexes formed by a number of equal (homomers) or different (heteromers) receptors. This review presents the data showing the occurrence of heteromers formed by A(1) and A(2A), A(2A) and A(2B), and A(2A) and A(3) receptors highlighting (i) their tetrameric structural arrangements, and (ii) the functional diversity that those heteromers provide to adenosinergic signaling.
