The glyconucleotides adenophostin A and B are the most potent known agonists at type 1 inositol trisphosphate [Ins(1,4,5)P3] receptors, although their stuctures differ markedly from that of Ins(1,4,5)P3. Equilibrium competition binding with [3H]Ins(1,4,5)P3 and unidirectional 45Ca2+ flux measurements were used to examine the effects of adenophostin A in hepatocytes, which express predominantly type 2 Ins(1,4,5)P3 receptors. Both Ins(1,4,5)P3 (Kd = 8.65 +/- 0.98 nM) and adenophostin A (Kd = 0.87… CONTINUE READING
