xUBF contains a novel dimerization domain essential for RNA polymerase I transcription.

Genes & development - 1 Nov 1991

McStay B, Frazier M W, Reeder R H

Abstract excerpt

Xenopus laevis upstream binding factor (xUBF) is an RNA polymerase I transcription factor that is required for formation of the stable initiation complex. The 701-amino-acid protein contains three regions of homology to the chromosomal protein HMG1 (the HMG boxes), which act in comparative independence to cause DNA binding. DNA binding is augmented by a 102-residue amino-terminal domain that causes xUBF to form...
