Assessment Binding Mode Motif Status Notes Comments
Likely to be sequence specific TF 2 Obligate heteromer No motif A more distant paralog of TBP and the only member of the TBP family that lacks the ability to bind the TATA box. (PMID: 21711503). In vitro, purified TLF-TFIIA binds directly to the NF1 promoter (PMID: 15767669), so likely an obligate heteromer.


Description: TATA-box binding protein like 1 [Source:HGNC Symbol;Acc:HGNC:11589]
Entrez Summary This gene encodes a member of the TATA box-binding protein family. TATA box-binding proteins play a critical role in transcription by RNA polymerase II as components of the transcription factor IID (TFIID) complex. The encoded protein does not bind to the TATA box and initiates transcription from TATA-less promoters. This gene plays a critical role in spermatogenesis, and single nucleotide polymorphisms in this gene may be associated with male infertility. Alternatively spliced transcript variants have been observed for this gene, and a pseudogene of this gene is located on the long arm of chromosome 3. [provided by RefSeq, Nov 2011]

Vaquerizas 2009 TF classification
"a" Has direct evidence of TF function;
"b" Has evidence for an orthologous TF;
"c" contains likely DBDs, but has no functional evidence;
"x" is an unlikely TF such as predicted gene, genes with likely non-specific DBDs or that have function outside transcription;
"other" category contains proteins without clear DBDs they curated from external sources.
CisBP considers it as a TF? Yes
TFclass considers it as a TF? Yes
Has GO:0003700 "transcription factor activity, sequence-specific DNA binding" No
Initial Assessment
1a1 Protein has a high confidence PWM (HT-SELEX, PBM or B1H model) or there is a crystal structure that supports sequence specific DNA binding;
1a2 There is high confidence data for a close ortholog (as defined in CisBP);
2a1 There is lower confidence direct evidence, such as a Jaspar, Hocomoco or Transfac model;
2a2 There is lower confidence evidence for an close ortholog;
3a There is decent circumstantial evidence for its role as a TF or not;
4a Two or more datasets predict it as a TF;
5a One of the source datasets predicts is as a TF
4a, two or more datasets predict it as a TF
TF has conditional DNA-binding requirements
