Nipah virus proteins W and V interact with STAT4. (A) TAP of tagged V, W, VG121E, WG121E, and EYFP. Postpurification, samples were immunoblotted for STAT1, STAT4, and the FLAG tag. (B) Network representation of the Nipah virus V and W interactions with STAT family members, as obtained in the TAP-MS experiments. Shown is the TAP of tagged V, W, VG121E, WG121E, and EYFP after purification samples were probed against STAT1, STAT4, and FLAG.
