Our goal was to quantitate inositol 1,4,5-trisphosphate (Ins(1,4,5)P3) binding to aldolase C tetramer (aldolase4) and its displacement by inositol 1,3,4-trisphosphate (Ins(1,3,4)P3) under conditions which approximated the in vivo state. Anions were found to have major effects. Decreasing [KCl] from 100

We have sequenced and recombinantly expressed as a fusion protein an expressed sequence tag clone (GB Z25963) from Arabidopsis thaliana that represents the plant homologue of human inositol 1,3,4 trisphosphate 5/6-kinase. The 1365 base pair clone has an open reading
The synthesis of rac-2,5,6-tri-O-butyryl-myo-inositol 1,3,4-trisphosphate hexakis(acetoxymethyl) ester [Bt3-Ins(1,3,4)P3/AM, 1], a membrane-permeant derivative of myo-inositol 1,3,4-trisphosphate [Ins(1,3,4)P3] is reported. 1 inhibited calcium-mediated chloride secretion of T84 cells, suggesting a regulatory link of Ins(1,3,4)P3 and the biosynthesis of the known inhibitor myo-inositol

Syntheses of the enantiomers of myo-inositol 1,3,4-trisphosphate are described. 1,4-Di-O-allyl-myo-inositol was regioselectively p-methoxybenzylated at the 3-position to give 1,4-di-O-allyl-3-O-(p-methoxybenzyl)-myo-inositol followed by benzylation of the remaining free hydroxyl groups to give the key intermediate 1,4-di-O-allyl-2,5,6-tri-O-benzyl-3-O-(p-methoxybenzyl)-myo-inositol. Removal of the p-methoxybenzyl and allyl
Integrin signaling modulates trophoblast adhesion to extracellular matrices during blastocyst implantation. Fibronectin (FN)-binding activity on the apical surface of trophoblast cells is strengthened after elevation of intracellular Ca(2+) downstream of integrin ligation by FN. We report here that phosphoinositide-specific phospholipase
