Cd38/Adp-Ribosyl Cyclase
The multifunctional ADP-ribosyl cyclase, CD38, catalyzes the cyclization of NAD(+) to cyclic ADP-ribose (cADPr). The latter gates Ca(2+) release through microsomal membrane-resident ryanodine receptors (RyRs). We first cloned and sequenced full-length CD38 cDNA from a rabbit osteoclast cDNA library. The predicted amino acid sequence displayed 59, 59, and 50% similarity, respectively, to the mou...
متن کاملRole of kidney ADP-ribosyl cyclase in diabetic nephropathy.
The role of ADP-ribosyl cyclases (ADPR-cyclases) in diabetic nephropathy was investigated. ADPR-cyclases synthesize cADP-ribose (cADPR), a Ca(2+)-mobilizing second messenger, and are stimulated by G protein-coupled receptors. We have previously reported that ADPR-cyclases can be activated by ANG II and showed that a specific kidney ADPR-cyclase inhibitor, 4,4'-dihydroxyazobenzene (DHAB), can pr...
متن کاملA novel signaling pathway of ADP-ribosyl cyclase activation by angiotensin II in adult rat cardiomyocytes.
ADP-ribosyl cyclase (ADPR-cyclase) produces a Ca(2+)-mobilizing second messenger, cADP-ribose (cADPR), from NAD(+). In this study, we investigated the molecular basis of ADPR-cyclase activation in the ANG II signaling pathway and cellular responses in adult rat cardiomyocytes. The results showed that ANG II generated biphasic intracellular Ca(2+) concentration increases that include a rapid tra...
متن کاملADP-Ribosyl cyclase in rat vascular smooth muscle cells: properties and regulation.
We investigated whether ADP-ribosyl cyclase (ADPR-cyclase) in rat vascular smooth muscle cells (VSMCs) has enzymatic properties that differ from the well-characterized CD38-antigen ADPR-cyclase, expressed in HL-60 cells. ADPR-cyclase from VSMCs, but not CD38 ADPR-cyclase from HL-60 cells, was inhibited by gangliosides (10 micromol/L) GT(1B), GD(1), and GM(3). Preincubation of membranes from CD3...
متن کاملMolecular Characterization of a Novel Intracellular ADP-Ribosyl Cyclase
BACKGROUND ADP-ribosyl cyclases are remarkable enzymes capable of catalyzing multiple reactions including the synthesis of the novel and potent intracellular calcium mobilizing messengers, cyclic ADP-ribose and NAADP. Not all ADP-ribosyl cyclases however have been characterized at the molecular level. Moreover, those that have are located predominately at the outer cell surface and thus away fr...
