To define the RUNX1T1 protein interactome in neuroblastoma cells, we performed mass spectrometry (LC-MS/MS) on BE(2)-C cells transiently transfected with FLAG-tagged wild-type RUNX1T1 followed by STRING analysis to define putative RUNX1T1 interacting partners (Supplementary Fig. 5a). Here, RUNX1T1 is linked to neuroblastoma.
