Abstract
Activation of transcription by RNA polymerase I (polI) requires that an assembly of protein factors locate the polI promoter and form a stable preinitiation complex. It is apparently this pre-initiation complex, not the underlying DNA sequence, which is then recognized by polI as it cycles through many rounds of RNA chain initiation, elongation, and termination. In vertebrate cells two components have so far been identified as having roles in forming the polI pre-initiation complex. One is SL1, a complex of four polypeptides one of which is the TATA-binding protein.4 The other is UBF, the subject of this chapter.
