Biochem/physiol Actions

An antagonist of cyclic ADP-ribose (cADPR), and an endogenous metabolite of β-NAD+. cADPR has been shown to regulate calcium release from the endoplasmic and sarcoplasmic reticulum. In cells, cADPR is synthesized by ADP-ribosyl cyclase or CD38, a lymphocyte differentiation antigen.

Cyclic ADP-ribose (cADPR), an endogenous metabolite of beta-NAD+, activates Ca2+ release from endoplasmic reticulum in sea urchin eggs via the ryanodine receptor (RyR) pathway. A similar role has been proposed in cardiac sarcoplasmic reticulum (SR), although this remains controversial. We

Mobilization of internal Ca+2 is an important signaling mechanism in cells. In addition to the inositol trisphosphate pathway, cyclic ADP-ribose (cADPR) and nicotinic acid adenine dinucleotide (NAADP) have been shown to mobilize Ca+2 via independent mechanisms. Although the structures of

CD38 was first identified as a lymphocyte differentiation antigen that showed typical properties of an orphan receptor involved in many programs of cell proliferation and activation. However, CD38 proved also to be a bifunctional ectoenzyme that catalyzes the transient formation

Ca2+ mobilization as a signaling mechanism has been placed on center stage with the discovery of the first Ca2+ messenger, inositol trisphosphate (IP3). This article focuses on two new Ca2+ release activators, which mobilize internal Ca2+ stores via mechanisms totally

Nucleotides and nucleosides play important roles by maintaining brain homeostasis, and their extracellular concentrations are mainly regulated by ectonucleotidases and nucleoside transporters expressed by astrocytes. Extracellularly applied NAD(+) prevents astrocyte death caused by excessive activation of poly(ADP-ribose) polymerase-1, of which
