Interactome profiling of Crimean-Congo hemorrhagic fever virus glycoproteins and identification of HAX1 as a host restriction factor against the virion packaging

The glycoproteins of CCHFV, Gn and Gc, are considered to play multiple roles in the viral life cycle by interactions with host cells; however, these interactions remain largely unclear to date. Here, we analyzed the cellular interactomes of CCHFV glycoproteins by affinity purification-quantitative mass spectrometry and identified 45 host proteins as high-confidence Gn/Gc interactors.
