Descriptions Names[Advanced Search]

A protein complex, distinct from RNA polymerase, that associates with DNA at promoters or at cis-acting regulatory sequences, by direct binding or by interaction with other DNA-binding polypeptides or complexes, and regulates transcription. A complex required for the transcription of rDNA by RNA polymerase I. In yeast the complex consists of Rrrn5p, Rrn9p, Rrn10p, histones H3 and H4, and Uaf30p. A transcription factor complex that acts at promoters of genes transcribed by RNA polymerase I. Any constituent part of a nucleolus, a small, dense body one or more of which are present in the nucleus of eukaryotic cells. It is rich in RNA and protein, is not bounded by a limiting membrane, and is not seen during mitosis.
