CC   -!- FUNCTION: Inhibits the expression or activity of extracellular murein
CC       hydrolases by interacting, possibly with LrgB, with the holin-like
CC       protein CidA. The LrgAB and CidA proteins may affect the proton motive
CC       force of the membrane. May be involved in programmed cell death (PCD),
CC       possibly triggering PCD in response to antibiotics and environmental
CC       stresses. {ECO:0000255|HAMAP-Rule:MF_01141}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000255|HAMAP-Rule:MF_01141};
CC       Multi-pass membrane protein {ECO:0000255|HAMAP-Rule:MF_01141}.
CC   -!- SIMILARITY: Belongs to the CidA/LrgA family. LrgA subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_01141}.
