ZMYND11 and Epstein-Barr virus infection: Consistently, Western blotting analysis of the BS69 protein in EBV-infected B cells, B lymphoma or lymphoblastoid cells revealed that the protein level of BS69 became barely detectable in those B cells with EBV infection at 4 or 7 dpi and the BJAB-E2 or LCL cells, but persisted in the primary B cells, parental BJAB, BJAB-E1 and AKATA cells (Fig 4B).
