[https://www.uniprot.org/uniprot/CDND2_ENTCL CDND2_ENTCL] CBASS (cyclic oligonucleotide-based antiphage signaling system) provides immunity against bacteriophage. The CD-NTase protein synthesizes cyclic nucleotides in response to infection; these serve as specific second messenger signals. The signals activate a diverse range of effectors, leading to bacterial cell death and thus abortive phage infection. A type II-C(AAG) CBASS system (PubMed:32839535).<ref>PMID:32544385</ref> <ref>PMID:32839535</ref> Cyclic trinucleotide synthase that catalyzes the synthesis of 3',3',3'-cyclic AMP-AMP-GMP as the major product, a second messenger for cell signal transduction.<ref>PMID:30787435</ref> Protects E.coli against phage T2 infection. When the cdnD-cap2-cap3-cap4 operon is introduced in E.coli there is a more than 10(3) decrease in the efficiency of T2 plaque formation. The operon does not protect against phage T5 and only about 10-fold against T7.<ref>PMID:32544385</ref>
