CC   -!- FUNCTION: Virulence factor that is important for the establishment of
CC       infection in the host. EsxB is required for EsxA synthesis as well as
CC       secretion (By similarity). Mediates together with EsxA the release of
CC       S.aureus from the host cell. Inhibits also host cytokine production and
CC       thus modulates dendritic cell-mediated immunity (By similarity).
CC       {ECO:0000250|UniProtKB:A0A0H2XIE9, ECO:0000250|UniProtKB:P0C047}.
CC   -!- SUBUNIT: Homodimer. When mixed with EsxA does not form heterodimers.
CC       {ECO:0000250|UniProtKB:Q2G182}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:P0C047}.
CC       Note=Secreted via the ESAT-6 secretion system (Ess) / type VII
CC       secretion system (T7SS). {ECO:0000250|UniProtKB:P0C047}.
CC   -!- SIMILARITY: Belongs to the WXG100 family. {ECO:0000305}.
