CC   -!- FUNCTION: CBASS (cyclic oligonucleotide-based antiphage signaling
CC       system) provides immunity against bacteriophage. The CD-NTase protein
CC       synthesizes cyclic nucleotides in response to infection; these serve as
CC       specific second messenger signals. The signals activate a diverse range
CC       of effectors, leading to bacterial cell death and thus abortive phage
CC       infection. A type I-B CBASS system (PubMed:32839535).
CC       {ECO:0000269|PubMed:31533127, ECO:0000303|PubMed:32839535}.
CC   -!- FUNCTION: Protects B.subtilis against phage infection. When IK1_05630
CC       and IK1_05631 are introduced in B.subtilis BEST7003 there is 1000-fold
CC       protection against phage SBSphiC. Both genes are required for
CC       protection. Activation leads to bacterial cell lysis and death, which
CC       occurs before the phage has finished its replication cycle, thus
CC       protecting non-infected bacteria by aborting the phage infection and
CC       preventing its propagation. {ECO:0000269|PubMed:31533127}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000255}; Multi-pass membrane
CC       protein {ECO:0000255}.
CC   -!- INDUCTION: Part of the CBASS operon consisting of cdnD-IK1_05631.
CC       {ECO:0000305|PubMed:31533127}.
