Summary: This gene encodes one of the multiple subunits of the RNA polymerase III transcription factor complex required for transcription of genes with promoter elements upstream of the initiation site. The product of this gene, a TFIIB-like factor, is directly recruited to the TATA-box of polymerase III small nuclear RNA gene promoters through its interaction with the TATA-binding protein.

Results show that the mRNA and protein expression levels of BRF2 were markedly higher in non-small cell lung cancer (NSCLC) cells and highly related to differentiation degree, lymph node metastasis, clinical stage, and vascular invasion. miR-373 was identified to directly target BRF2, resulting in the enhanced migration and invasion of NSCLC A549 cells and indicating that BRF2 affects the metastasis of NSCLC.

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.
