CC -!- FUNCTION: Might be involved in ligand transport. A host TLR2 agonist,
CC modifies host gene expression in response to pathogen.
CC {ECO:0000250|UniProtKB:P9WK61}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Lipid-anchor
CC {ECO:0000305}.
CC -!- DOMAIN: Forms a U-shaped beta-half-barrel with a large hydrophobic
CC cavity. {ECO:0000250|UniProtKB:P9WK61}.
CC -!- PTM: Modified by Lgt on Cys-22 with an S-linked diacylglycerol with a
CC mixture of C16, C18 and C19 fatty acids, signal peptide is removed by
CC LspA, modifed by Lnt with an amide-linked mixture of C16 and C19 fatty
CC acids. {ECO:0000250|UniProtKB:P9WK61}.
CC -!- SIMILARITY: Belongs to the mycobacterial 19 kDa antigen family.
CC {ECO:0000305}.
