A membrane protein identified in cortical brain membranes and termed 'coupling cofactor', modulates G protein-coupling of the A1-adenosine receptor by reducing the catalytic efficiency of the receptor. Coupling cofactor traps the A1-adenosine receptor in the high affinity complex and, thus, is responsible for the resistance of high affinity A1-agonist(More)
