Biological Function General transcription factor that plays a role in transcription initiation by RNA polymerase II (Pol II). Involved in the pre-initiation complex (PIC) formation and Pol II recruitment at promoter DNA (PubMed:1876184, PubMed:1946368, PubMed:1517211, PubMed:3818643, PubMed:3029109, PubMed:8413225, PubMed:8515820, PubMed:8516311, PubMed:8516312, PubMed:7601352, PubMed:9420329, PubMed:12931194, PubMed:27193682). Together with the TATA box-bound TBP forms the core initiation complex and provides a bridge between TBP and the Pol II-TFIIF complex (PubMed:8504927, PubMed:8413225, PubMed:8515820, PubMed:8516311, PubMed:8516312). Released from the PIC early following the onset of transcription during the initiation and elongation transition and reassociates with TBP during the next transcription cycle (PubMed:7601352). Associates with chromatin to core promoter-specific regions (PubMed:12931194, PubMed:24441171). Binds to two distinct DNA core promoter consensus sequence elements in a TBP-independent manner; these IIB-rPubMed:10318856, PubMed:10619841, PubMed:12931194, PubMed:1517211, PubMed:16230532, PubMed:1876184, PubMed:1946368, PubMed:24441171, PubMed:27193682, PubMed:3029109, PubMed:3818643, PubMed:7601352, PubMed:7675079, PubMed:8413225, PubMed:8504927, PubMed:8515820, PubMed:8516311, PubMed:8516312, PubMed:9420329}.
Research Areas Protein Transcription
Storage Store at 2 - 8ºC. Do not Freeze.
Dilution Instructions Dilute in PBS or medium that is identical to that used in the assay system.
Application Instructions This antibody may be used in ELISA, Western blot, or electrophoretic mobility (gel shift) assays to identify human TFIIB. It can also immuno-deplet TFIIB from cell nuclear extracts and inhibit transcription of TFIIB from cell nuclear extracts. This antibody is polyol-responsive and can be used for gentle purification of TFIIB.
