TBP-like factors (TLF; also called TLP, TRF, TRP), which are found in most metazoans. TLFs and TBPs have well-conserved core domains; however, they only share about 60% similarity. TLFs, like TBPs, interact with TFIIA and TFIIB, which are part of the basal transcription machinery. Yet, in contrast to TBPs, TLFs seem not to interact with the TATA-box and even have a negative effect on the transcription of TATA-containing promoters. Recent results indicate that TLFs are involved in the transcription via TATA-less promoters.

TATA box binding protein (TBP): Present in archaea and eukaryotes, TBPs are transcription factors that recognize promoters and initiate transcription. TBP has been shown to be an essential component of three different transcription initiation complexes: SL1, TFIID and TFIIIB, directing transcription by RNA polymerases I, II and III, respectively. TBP binds directly to the TATA box promoter element, where it nucleates polymerase assembly, thus defining the transcription start site. TBP's binding in the minor groove induces a dramatic DNA bending while its own structure barely changes. The conserved core domain of TBP, which binds to the TATA box, has a bipartite structure, with intramolecular symmetry generating a saddle-shaped structure that sits astride the DNA. New members of the TBP family, called TBP-like proteins (TBLP, TLF, TLP) or TBP-related factors (TRF1, TRF2,TRP), are similar to the core domain of TBPs, with identical or chemically similar amino acids at many equivalent positions, suggesting similar structure. However, TLFs contain distinct, conserved amino acids at several positions that distinguish them from TBP.

The Show Concise/Full Display button at the top of the page can be used to select the desired level of detail: only top scoring hits
(labeled illustration) or all hits

Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.

(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
specific hits meet or exceed a domain-specific e-value threshold
(illustrated example)
and represent a very high confidence that the query sequence belongs to the same protein family as the sequences use to create the domain model
