21 kDa TBP-like protein, Second TBP of unique DNA protein, STUD, TATA box-binding protein-related factor 2, TBPL1, TLF, TLP, TLP21,,TBPL1
Part of a specialized transcription system that mediates the transcription of most ribosomal proteins through the 5-TCT-3 motif which is a core promoter element at these genes. Seems to also mediate the transcription of NF1. Does not bind the TATA box.
