unusual facts about Cyclic ADP-ribose


Cyclic ADP-ribose

cADPR and ADPR are synthesized from NAD+ by the bifunctional ectoenzymes of the CD38 family (also includes the GPI-anchored CD157 and the specific, monofunctional ADP ribosyl cyclase of the mollusc Aplysia).


Arabinosyl nucleosides

They contain – in contrast to most nucleosides – instead of the Dβ-D-Arabinofuranose.

Deoxyadenosine

It is a derivative of the nucleoside adenosine, differing from the latter by the replacement of a hydroxyl group (-OH) by hydrogen (-H) at the 2' position of its ribose sugar moiety.

Hsromega

The hsrω-n transcript directly or indirectly affects the localization/stability/activity of a variety of proteins including hnRNPs, Sxl, Hsp83, cAMP response element binding binding protein (CBP), Drosophila inhibitor of apoptosis protein 1 (DIAP1), JNK-signalling members, proteasome constituents, lamin C, ISWI, HP1 and poly(ADP)-ribose polymerase.

Nucleotide salvage

Uridine phosphorylase adds ribose-1-phosphate to the free base uracil, forming uridine monophosphate.

Ribose

cAMP and cGMP, formed from ATP and GTP, serve as secondary messengers in some signalling pathways.

Ribose-5-phosphate isomerase

Ribose-5-phosphate isomerase deficiency is mutated in a rare disorder, Ribose-5-phosphate isomerase deficiency.
