Ubinuclein interacts with the basic domain of transcription factors. A, The Ubi-Z/ZAP5–GST fusion protein pull-down assay was performed with the in vitro-translated EB1, ZJ (the basic domain of EB1 replaced with the basic domain of c-Jun), and C/EBP. B, The EMSA assay showed that in vitro-translated ubinuclein (Ubi-Z/ZAP5) binds to in vitro-translated EB1 and EB1gcn4, competing with their binding to an oligonucleotide containing the AP1 consensus sequence.
