Product Description
RRN3 (phospho-S649) polyclonal antibody is available at gentaur for next week delivery
Background: In eukaryotes, ribosomal RNA genes are transcribed by RNA polymerase (pol I). In Saccharomyces cerevisiae, transcription of rRNA genes requires at least three transcription factors, which include the two multisubunit factors Core factor and UAF that function in the assembly of the preinitiation complex. The third factor, Rrn3, functions as a single subunit and is not required for the preinitiation complex assembly. Unlike other pol I transcription factors, Rrn3 is functionally conserved between yeast and mammals as an rRNA gene transcription regulator. Human Rrn3 is 21% homologous to the yeast Rrn3 protein and is a member of a conserved gene family spanning the fungi, plant and animal kingdoms. hRrn3 is highly expressed in the lung, retina, thymus, and prostate. Rrn3 may be identical to the transcription factor TIF-IA, since both TIF-IA and Rrn3 associate with pol I and their activities are growth rate dependent.
