Adenosine A2B receptor


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.

Mechanism

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.

Gene

The gene is located near the Smith-Magenis syndrome region on chromosome 17.

Ligands

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, and research into their potential therapeutic applications is ongoing.
