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.

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

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

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
The inflammatory response in age-related macular degeneration (AMD) is characterized by mononuclear leukocyte infiltration of the outer blood-retina barrier formed by the retinal pigment epithelium (RPE). A key mechanistic element in AMD progression is RPE dysfunction and apoptotic cell loss.
