CC   -!- FUNCTION: Toxic component of a type I toxin-antitoxin (TA) system (By
CC       similarity). When overexpressed kills cells within minutes; causes
CC       collapse of the transmembrane potential and arrest of respiration (By
CC       similarity). Its toxic effect is probably neutralized by an antisense
CC       antitoxin Sok RNA (By similarity). {ECO:0000250|UniProtKB:P0ACG4}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane
CC       {ECO:0000250|UniProtKB:P0ACG4}; Single-pass membrane protein
CC       {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the Hok/Gef family. {ECO:0000305}.
