The lack of direct targets for
TATA-binding protein
(
TBP
)-like factors (TLFs) confounds the understanding of their role in gene expression. Here we report that human TLF (also called TBP-related factor 2 [TRF2]) activates a number of different genes, including the neurofibromatosis type 1 (NF1) gene. The overexpression of TLF increases the amount of
NF1
mRNA in cells. In vivo, TLF binds to and upregulates transcription from a fragment of the
NF1
promoter. In vitro, purified TLF-TFIIA binds directly to the same
NF1
promoter fragment that is required for TLF responsiveness in cells. Furthermore, targeted deletion of TLF in mice reduces
NF1
levels. In contrast, TLF inhibits transcription driven by a fragment from the TATA-containing c-fos promoter by sequestering TFIIA.
TBP
affects the
NF1
and c-fos promoters in a manner reciprocal to that of TLF, stimulating the c-fos promoter and inhibiting
NF1
transcription. We conclude that TLF is a functional regulator of transcription with targets distinct from those of
TBP
.
