Summary: Predicted to enable several functions, including RNA polymerase II core promoter sequence-specific DNA binding activity; RNA polymerase II general transcription initiation factor activity; and TBP-class protein binding activity. Predicted to be involved in several processes, including RNA polymerase II core complex assembly; meiotic sister chromatid cohesion; and transcription initiation at RNA polymerase II promoter. Predicted to be located in chromosome and nuclear body. Predicted to be part of transcription factor TFIID complex and transcription preinitiation complex. Predicted to be active in cell division site; germinal vesicle; and kinetochore. Orthologous to human GTF2B (general transcription factor IIB). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

TFIIB was expressed in normal sciatic nerve. It gradually increased, reached a peak at the 7th day after crush, and then returned to the normal level at 4 weeks. Its expression mainly increased in Schwann cells.
Title: Transcription initiation factor IIB involves in Schwann cell differentiation after rat sciatic nerve crush.
Spatiotemporal changes of TFIIB expression suggest that this protein may play a role in the degenerative process of RGCs by light-induced damage in the retina.
Title: Involvement of transcription initiation factor IIB in the light-induced death of rat retinal ganglion cells in vivo.
Findings show that TFIIB binding is not restricted to the 5' upstream region indicates that the propensity for pre-initiation complex to contribute to transcript diversity is far greater than previously appreciated.
Title: Localization of TFIIB binding regions using serial analysis of chromatin occupancy.

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.
