RRN3

RRN3 (RRN3 Homolog, RNA Polymerase I Transcription Factor) is a Protein Coding gene. Among its related pathways are Gene Expression and RNA Polymerase I Promoter Escape. Gene Ontology (GO) annotations related to this gene include binding and RNA polymerase binding.

RRN3 RNA polymerase I transcription factor homolog (S. cerevisiae)

Required for efficient transcription initiation by RNA polymerase I. Required for the formation of the competent preinitiation complex (PIC). Dissociates from pol I as a consequence of transcription. In vitro, cannot activate transcription in a subsequent transcription reaction (By similarity).

Nucleus, nucleolus

Phosphorylation is required for participation in rDNA transcription (By similarity).
Phosphorylated at Thr-200 by MAPK9/JNK2, which abrogates initiation complex formation
