产品信息

背景说明： Transcription Initiation Factor IIB (TFIIB) is an essential factor for transcription by RNA Polymerase II.TFIIB localizes to the nucleus where it forms a complex (the DAB complex) with transcription factor IID and IIA.TFIIB plays a role as a bridge between IID，which initially recognizes the promoter sequence，and RNA polymerase II.TFIIB is involved in the selection of transcription start site.
