Upstream binding factor (UBF) was originally identified as a multi-HMG (high mobility group)-box DNA binding domain protein that could enhance the in vitro assembly of the RNA polymerase I initiation complex. UBF is a transcription factor that recognizes the ribosomal RNA gene promoter required for the expression of 18S, 5.8S, and 28S ribosomal RNAs.
