Colocalization of PCGF5 and IgLL1 with E. chaffeensis expressing TRP47 with in infected THP-1 cells. E. chaffeensis-infected cells were dually-labeled with anti-TRP47 (green) and PCGF5 or IgLL1 (red) and examined by confocal microscopy. PCGF5 and IgLL1 colocalize with E. chaffeensis TRP47 labeled morulae (yellow, right merged panels). Molecular interactions between PCGF5, IGLL1, Fyn, CAP1 and PTPN2 were first reported by Wakeel et. al., 2009).
