Virulence factor that is important for the establishment of infection in the host. EsxB is required for EsxA synthesis as well as secretion (PubMed:15657139). Mediates together with EsxA the release of S.aureus from the host cell. Also inhibits host cytokine production and thus modulates dendritic cell-mediated immunity (By similarity)
Secreted
Homodimer. When mixed with EsxA does not form heterodimers
