Calexcitin interaction with neuronal ryanodine receptors.
Calexcitin (CE), a Ca2+- and GTP-binding protein, which is phosphorylated during memory consolidation, is shown here to co-purify with ryanodine receptors (RyRs) and bind to RyRs in a calcium-dependent manner. Nanomolar concentrations of CE released up to 46% of the 45Ca label from microsomes preloaded with 45CaCl2. This release was Ca2+-dependent and was blocked by antibodies against the RyR o...
متن کاملTime domains of neuronal Ca2+ signaling and associative memory: steps through a calexcitin, ryanodine receptor, K+ channel cascade.
Synaptic changes that underlie associative learning and memory begin with temporally related activity of two or more independent synaptic inputs to common postsynaptic targets. In turn, temporally related molecular events regulate cytosolic Ca2+ during progressively longer-lasting time domains. Associative learning behaviors of living animals have been correlated with changes of neuronal voltag...
متن کاملMolecular interaction of dihydropyridine receptors with type-1 ryanodine receptors in rat brain.
In striated muscles, Ca2+ release from internal stores through ryanodine receptor (RyR) channels is triggered by functional coupling to voltage-activated Ca2+ channels known as dihydropyridine receptors (DHPRs) located in the plasma membrane. In skeletal muscle, this occurs by a direct conformational link between the tissue-specific DHPR (Ca(v)1.1) and RyR(1), whereas in the heart the signal is...

متن کاملRegulation of calcium release by interdomain interaction within ryanodine receptors.
In excitation-contraction (E-C) coupling, various types of activation signals, which are received presumably at the bulky cytoplasmic domain of the ryanodine receptor (RyR), are translated (or transduced) into the opening of the Ca2+ release channel located in the trans-membrane domain of the RyR. In order to elucidate the detailed mechanism of the signal transduction process, it is essential (...
