ITGB4 and infection: Among them, integrins (ITGB4), actin-binding proteins such as parvins (PARVA) and filamins (FLNB), proteins related to actin-membrane attachment (PXN, EPB41L1, VAPA) and different cytoskeleton components (TLN1), which were not previously associated with viral entry, were phosphorylated within minutes of infection.
