Target Information

The initiation of gene transcription involves the ordered assembly of a multiprotein complex on proximal promoter elements such as the TATA box. In addition to RNA polymerase II (Pol II), the transcription factor class II (TFII) family of proteins are required for initiation of transcription, as the first step in the formation of this initiation complex is the stable binding of TFIID to the TATA box.
An additional TFII-related protein, BTF3, forms a stable complex with Pol II and facilitates Pol II assembly into the complex. The BTF3 gene encodes two isoforms, BTF3a and BTF3b, which differ by the absence of 44 amino acids at the N-terminal of BTF3b, affecting transcription induction ability.
Both isoforms associate with casein kinase II, which phosphorylates BTF3a and TFIIB and is required for efficient transcription of tRNA and 5S rRNA genes by Pol III.
BTF3 belongs to the NAC-beta family, which includes related proteins such as BTF3L1, BTF3L2, BTF3L3, and BTF3L4.
