Gene Symbol GTF2B
Gene Full Name general transcription factor IIB
Background 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]
Function General factor that plays a major role in the activation of eukaryotic genes transcribed by RNA polymerase II. [UniProt]
Research Area Gene Regulation antibody
Calculated MW 35 kDa
