Mehanizam

uredi

Ovaj integralni membranski protein stimuliše aktivnost adenilat ciklaze u prisustvu adenozina. On takođe interaguje sa netrinom-1, koji učestvuje u elongaciji aksona.

Gen

uredi

Gen je lociran blizo regiona Smit-Magenisovog sindroma na hromozomu 17.[1]

Ligandi

uredi

Istraživanja selektivnih A2B liganda su kasnila za razvojem liganda druga tri adenozinska receptora, međutim vremenom su brojna A2B-selektivna jedinjenja razvijena,[2][3][4][5][6][7][8][9][10][11] i istraživanja njihove potencijalne terapeutske primene su u toku.[12][13][14][15][16][17]
