About apo-TBP

TATA box-binding protein (TBP) plays a role in transcription initiation by binding to the TATA sequence on DNA. The inner surface of TBP has beta sheets which interact with DNA. The outer surface of TBP consists of alpha helices that are able to interact with other transcription initiation factors and regulatory proteins. The C-terminal end of TBP specifically binds to the TATA sequence and is highly conserved among different organisms, from yeast to humans.
