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 (PubMed:15657139). 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:0000269|PubMed:15657139}.
CC   -!- SUBUNIT: Homodimer. When mixed with EsxA does not form heterodimers.
CC       {ECO:0000250|UniProtKB:Q2G182}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:15657139}.
CC       Note=Secreted via the ESAT-6 secretion system (Ess) / type VII
CC       secretion system (T7SS). {ECO:0000305}.
CC   -!- DISRUPTION PHENOTYPE: Mutant shows a significant reduction in the
CC       ability to establish kidney or liver abscesses in infected mice.
CC       {ECO:0000269|PubMed:15657139}.
CC   -!- SIMILARITY: Belongs to the WXG100 family. {ECO:0000305}.
