Clade 1 Vap virulence proteins of Rhodococcus equi are associated with the cell surface and support intracellular growth in macrophages PLOS One The N terminal domain is required for cell surface localisation of VapA, a member of the Vap family of Rhodococcus equi virulence proteins PLOS One VAPA mediates lipid exchange between Leishmania amazonensis and host macrophages bioRxiv The ER tether VAPA is required for proper cell motility and anchors ER PM contact sites to focal adhesions bioRxiv VirS, an OmpR PhoB subfamily response regulator, is required for activation of vapA gene expression in Rhodococcus equi BMC Microbiology Springer Nature Link
