Owing to its crucial role in nCov19 infection, we assembled its known and novel PPIs separately and found that it was connected to four host proteins (SIL1, LOX, MDN1 and NINL) through an intermediate interactor, i.e. separated by two edges, where one or both intermediary PPIs are novel predicted ones (see red edges in Figure 2B). Here, SIL1 is linked to infection.
