WebThe transcription factor Smad2 is released from cytoplasmic retention by TGFβ receptor-mediated phosphorylation, accumulating in the nucleus where it associates with cofactors to regulate transcription. We uncovered direct interactions of Smad2 with the nucleoporins CAN/Nup214 and Nup153. These interactions mediate constitutive nucleocytoplasmic … WebTo investigate whether diazaborine also affects shuttling factor release, we purified late pre-60S particles by TAP using Arx1 as bait protein. As shown in Fig. 1A, drug treatment of the wild-type strain resulted in increased levels of the shuttling proteins Rlp24 and Nog1 and of the export factors Mex67 and Mtr2 in these pre-60S purifications.
