Anti-GTF2B Antibody Picoband®

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.

E.coli-derived human GTF2B recombinant protein (Position: N17-D298) . Human GTF2B shares 100% amino acid (aa) sequence identity with both mouse and rat GTF2B.
