Experimental studies have demonstrated cGAMP synthetase activity in the Vibrio cholerae DncV protein, a member of the SMODS family. The diversity inherent to the SMODS family suggests members of the family could generate a range of nucleotides, cyclic and/or linear. The nucleotide second messengers generated by the SMODS domains are predicted to activate effectors in a class of conflict systems reliant on the production and sensing of the nucleotide second messengers [1] [2].

Acts as a 'third component' in broad class of conflict systems reliant on the production of second messenger nucleotide or nucleotide derivatives. Together with Pch2/TRIP13, could act as co-effectors or in regulation of other effectors of the systems [1]. This domain found in bacterial proteins from the cyclic-oligonucleotide-based anti-phage signalling system (CBASS), such us CD-NTase-associated protein 7 from P. aeruginosa (Cap7), which is part of the type III-CBASS. CBSSs are a family of defence systems against bacteriophages [2,3].
