Fig. 3. EBOV VP35 S187A impairs VP35 phosphorylation in HepG2 cells. HepG2 cells were transfected with plasmids pCAGGS-VP35, pCAGGS-VP35 S187A, pCAGGS-VP35 S205A/T206A/S208A, pCAGGS-VP35 S317A and pCAGGS-VP35 S187A/S205A/T206A/S208A/S317A as indicated, and the cell lysates were subjected to anti-VP35 immunoprecipitation. |

Abstract
|
Ebola virus (EBOV) is a zoonotic pathogen, the infection often results in severe, potentially fatal, systematic disease in human and nonhuman primates. VP35, an essential viral RNA-dependent RNA polymerase cofactor, is indispensable for Ebola viral replication and host innate immune escape. In this study, VP35 was demonstrated to be phosphorylated at Serine/Threonine by immunoblotting, and the major phosphorylation sites was S187, S205, T206, S208 and S317 as revealed by LC-MS/MS. By an EBOV minigenomic system, EBOV minigenome replication was shown to be significantly inhibited by the phosphorylation-defective mutant, VP35 S187A, but was potentiated by the phosphorylation mimic mutant VP35 S187D. Together, our findings demonstrate that EBOV VP35 is phosphorylated on multiple residues in host cells, especially on S187, which may contribute to efficient viral genomic replication and viral proliferation.
