The SLATT domain contains two transmembrane helices. SLATT domains are generally predicted to function as pore-forming effectors in a class of conflict systems which are reliant on the production of second messenger nucleotide or nucleotide derivatives. SLATT domains are predicted to initiate cell suicide responses upon their activation. This SLATT family is often coupled to the SMODS nucleotide synthetase and is sometimes further embedded in other conflict systems like CRISPR/Cas or R-M systems [1].
