The adenosine A2B receptor, also known as ADORA2B, is a G-protein coupled adenosine receptor, and also denotes the human adenosine A2b receptor gene which encodes it.[5]
This integral membrane protein stimulates adenylate cyclase activity in the presence of adenosine. This protein also interacts with netrin-1, which is involved in axon elongation.
The gene is located near the Smith-Magenis syndrome region on chromosome 17.[5]
Research into selective A2B ligands has lagged somewhat behind the development of ligands for the other three adenosine receptor subtypes, but a number of A2B-selective compounds have now been developed,[6][7][8][9][10][11][12][13][14][15] and research into their potential therapeutic applications is ongoing.[16][17][18][19][20][21][22]
