APIS024 Tad1 Thoeris CLAN001 SBSphiJ7 of B. subtilis PMID:36174646 Tad1 proteins are not an enzymes, but are 'sponges' that bind and sequester the immune signaling molecule (cyclic ADP-ribose or gcADPR) produced by TIR-domain proteins, thus decoupling phage sensing from immune effector activation and rendering Thoeris inactive.
APIS029 Tad2 Thoeris CLAN001 Bacillus phage SPO1 Yirmiya et al., 2023 Tad2 is a "sponge" that sequesters the immune signaling molecules produced by Thoeris TIR-domain proteins in response to phage.

APIS211 SequestinJ Thoeris CLAN001 PMID:41785351 Thoeris anti-defense sponge; sequesters 3′cADPR and blocks ThsA activation
APIS245 SequestinM Thoeris CLAN001 PMID:41785351 Sequestin-family anti-defense protein; inhibits type I Thoeris signaling, most likely by binding 3′cADPR.
APIS283 SequestinD Thoeris CLAN001 PMID:41785351 Thoeris anti-defense sponge; sequesters 3′cADPR and blocks ThsA activation
APIS283 SequestinE Thoeris CLAN001 PMID:41785351 Thoeris anti-defense sponge; sequesters 3′cADPR and blocks ThsA activation
APIS315 SequestinK Thoeris CLAN001 PMID:41785351 Sequestin-family Thoeris inhibitor; anti-defense protein that blocks the 3′cADPR → ThsA signaling pathway.
APIS315 SequestinB Thoeris CLAN001 PMID:41785351 Anti-Thoeris Sequestin-family sponge; neutralizes Thoeris signaling by trapping 3′cADPR and blocking downstream NAD-depletion defense.
APIS315 SequestinL Thoeris CLAN001 PMID:41785351 Viral anti-Thoeris sponge; binds/sequesters ADPR-derived Thoeris signal molecules and prevents growth-arrest/cell-death defense.
APIS315 SequestinH Thoeris CLAN001 PMID:41785351 Phage Sequestin homolog; functions as a Thoeris inhibitor by preventing immune-signal activation of the effector.
APIS315 SequestinF Thoeris CLAN001 PMID:41785351 Sequestin-family viral anti-defense protein; inhibits Thoeris by binding the TIR-produced ADPR-derived immune signal.
APIS356 SequestinI Thoeris CLAN001 PMID:41785351 Sequestin-family antidefense protein; neutralizes Thoeris signaling molecules and allows phage escape from Thoeris defense.
APIS372 SequestinC Thoeris CLAN001 PMID:41785351 Small phage anti-defense protein from the Sequestin family; inhibits type I Thoeris by interfering with 3′cADPR-mediated immune activation.
APIS373 SequestinG Thoeris CLAN001 PMID:41785351 Anti-Thoeris sponge protein; blocks Thoeris immune signaling, likely through sequestration of 3′cADPR.
APIS378 SequestinA Thoeris CLAN001 PMID:41785351 Phage-encoded anti-Thoeris sponge protein; binds/sequesters the type I Thoeris immune signal 3′cADPR, preventing activation of the ThsA NADase effector.
