CC   -!- FUNCTION: Inhibits the expression or activity of extracellular murein
CC       hydrolases by interacting, possibly with LrgA, with the holin-like
CC       proteins CidA and/or CidB. The LrgAB and CidAB proteins may affect the
CC       proton motive force of the membrane. May be involved in programmed cell
CC       death (PCD), possibly triggering PCD in response to antibiotics and
CC       environmental stresses. {ECO:0000255|HAMAP-Rule:MF_01142}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000255|HAMAP-Rule:MF_01142};
CC       Multi-pass membrane protein {ECO:0000255|HAMAP-Rule:MF_01142}.
CC   -!- SIMILARITY: Belongs to the CidB/LrgB family. LrgB subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_01142}.
