ADP-ribose 1"-2" cyclic phosphate is a cyclic phosphate nucleotide that arises from tRNA processing. In eukaryotic cells, pre-tRNAs spliced by a pathway that produces a 3,5-phosphodiester, 2-phosphomonoester linkage contain a 2-phosphate group adjacent to the tRNA anticodon. This 2-phosphate is transferred to NAD to give adenosine diphosphate (ADP)-ribose 1", 2"-cyclic phosphate (Appr>p), which is subsequently metabolized to ADP-ribose 1-phosphate (Appr-1p). The latter reaction is catalyzed by a cyclic phosphodiesterase (CPDase). (PMID: 9148938). One molecule of ADP-ribose 1",2"-cyclic phosphate (Appr>p) is formed during each of the approximately 500 000 tRNA splicing events.
