Summary: Enables RNA polymerase binding activity. Acts upstream of or within several processes, including negative regulation of intrinsic apoptotic signaling pathway by p53 class mediator; regulation of transcription, DNA-templated; and transcription initiation from RNA polymerase I promoter. Predicted to be located in nucleolus. Predicted to be active in nucleus. Used to study Parkinson's disease. Orthologous to several human genes including RRN3 (RRN3 homolog, RNA polymerase I transcription factor). [provided by Alliance of Genome Resources, Apr 2022]

What's a GeneRIF?

Conditional deletion of the Rrn3 gene inhibits RNA polymerase I transcription but does not affect pre-initiation complex formation.
Title: A unique enhancer boundary complex on the mouse ribosomal RNA genes persists after loss of Rrn3 or UBF and the inactivation of RNA polymerase I transcription.
The results exemplify how stress-induced inactivation of TIF-IA and long non-coding RNA -dependent changes of chromatin structure ensure repression of ribosomal RNA synthesis in response to thermo-stress.
Title: Heat shock represses rRNA synthesis by inactivation of TIF-IA and lncRNA-dependent changes in nucleosome positioning.
These data support a model in which activated Akt enhances rRNA synthesis both by preventing TIF-IA degradation and phosphorylating CK2alpha, which in turn phosphorylates TIF-IA.
Title: Akt activation enhances ribosomal RNA synthesis through casein kinase II and TIF-IA.
DNA binding by the ribosomal DNA transcription factor rrn3 is essential for ribosomal DNA transcription
Title: DNA binding by the ribosomal DNA transcription factor rrn3 is essential for ribosomal DNA transcription.
Ablation of TIF-IA leads to impaired nucleolar activity and results in increased levels of the proapoptotic transcription factor p53 in both neural progenitors and hippocampal neurons but induces rapid apoptosis only in neural progenitors.
Title: Activation of an endogenous suicide response after perturbation of rRNA synthesis leads to neurodegeneration in mice.
Genetic inactivation of Tif1a leads to nucleolar disruption, cell cycle arrest, and p53-mediated apoptosis.
Title: Genetic inactivation of the transcription factor TIF-IA leads to nucleolar disruption, cell cycle arrest, and p53-mediated apoptosis.
ERK-dependent phosphorylation of the transcription initiation factor TIF-IA is required for RNA polymerase I transcription and cell growth.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
