Abstract

Evidence is presented to show that acid extracts of avian erythrocytes prelabelled for 24-48 h with myo-[3H]inositol contain the following myo-[3H]inositol trisphosphates (expressed as a percentage of total myo-[3H]inositol trisphosphates extracted): 36% myo-[3H]inositol 1,4,5-trisphosphate; 33.7% myo-[3H]inositol 1,3,4-trisphosphate; 13% myo-[3H]inositol 3,4,5-trisphosphate; 9.7% myo-[3H]inositol 3,4,6-trisphosphate; 4.4% myo-[3H]inositol 1,4,6-trisphosphate and 3.3% myo-[3H]inositol 1,3,6-trisphosphate. The only phosphatidyl-myo-[3H]inositol bisphosphate that could be detected in [3H]Ins-prelabelled avian erythrocytes was phosphatidyl-myo-[3H]inositol 4,5-bisphosphate. Cellular myo-[3H]inositol 3,4,5-trisphosphate may be synthesized by dephosphorylation of myo-[3H]inositol 3,4,5,6-tetrakisphosphate. D- and L-myo-[3H]inositol 1,4,6-trisphosphate and D- and L-myo-[3H]inositol 1,3,6-trisphosphate may be dephosphorylation products of myo-[3H]inositol 1,3,4,6-tetrakisphosphate.
