Transcription
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.[5]
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,[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]
