Reference Data

• RefSeq: NP_001505
• Locus ID: 2959
• UniProt ID: Q00403
• Cytogenetics: 1p22.2
• Synonyms: TF2B; TFIIB
• Summary: This gene encodes the general transcription factor IIB, one of the ubiquitous factors required for transcription initiation by RNA polymerase II. The protein localizes to the nucleus where it forms a complex (the DAB complex) with transcription factors IID and IIA. Transcription factor IIB serves as a bridge between IID, the factor which initially recognizes the promoter sequence, and RNA polymerase II. [provided by RefSeq, Jul 2008]
