Background information. Interconnections between the Ca2+ and cAMP signalling pathways can determine the specificity and diversity of the cellular effects mediated by these second messengers. Most cAMP effects are mediated by PKA (protein kinase A),

In the present study we investigated the effects of K+ and other univalent cations on [3H]InsP3 {[3H]Ins(1,4,5)P3} binding to sheep cerebellar microsomes. In equilibrium binding experiments performed over 4 s at pH 7.1 and 20 °C, the addition of K+

The inositol 1,4,5-trisphosphate (InsP 3 ) receptor is essential for Ca 2+ release from intracellular stores. There are three InsP 3 receptor types which are targets for several types of regulation. Ca 2+ , phosphorylation, and protein–protein inte

We have characterized in detail the Ca2+-dependent inhibition of [3H]Ins(1,4,5)P3 ([3H]InsP3) binding to sheep cerebellar microsomes, over a short duration (3 s), with the use of a perfusion protocol. This procedure prevented artifacts previously ide

Incubation of cerebellar microsomes with d-myo-inositol 1,4,5-trisphosphate (InsP3) (0.01 1 microM), at 4 or 20 degrees C in a cytosolic-like medium devoid of Ca2+ and Mg2+, followed by InsP3 removal, induced an increase in InsP3 binding determined w

The monohydroxy bile acid taurolithocholate permeabilizes the endoplasmic reticulum to Ca2+ in rat liver cells. To assess whether this action on the endoplasmic reticulum was restricted to this tissue, the effects of bile acid were investigated in tw

Ca2+ mobilisation by inositol 1,4,5-trisphosphate (InsP3) is a complex phenomenon which involves positive and negative feedback regulation by cytosolic Ca2+. It has been shown that Ca2+ increased the affinity of [3H]-InsP3 binding to liver membranes

Using sheep cerebellum microsomes previously loaded with 45 Ca 2+ or 90 Sr 2+ , we measured the dependence of inositol 1,4,5-trisphosphate (InsP 3 )-induced efflux of these ions on Ca 2+ or Sr 2+ on the cytosolic side. At a low InsP 3 concentration,

Using microsomal membrane vesicles derived from sheep cerebellum, we measured the rate of inositol 1,4,5-trisphosphate (InsP3)-dependent 45Ca2+ efflux from 45Ca(2+)-loaded compartments during rapid perfusion with a medium containing InsP3 and various

Inositol 1,4,5-trisphosphate (InsP3) is a second messenger responsible for the mobilization of intracellular Ca2+ after receptor-mediated hydrolysis of phosphatidylinositol 4,5-bisphosphate. InsP3 binds to a specific receptor located on the membrane
