Assessment Binding Mode Motif Status Notes Comments
Known motif 1 Monomer or homomultimer In vivo/Misc source Only known motifs are from Transfac or HocoMoco - origin is uncertain (PMID: 18326499) shows through SELEX and EMSA that this family binds DNA specifically. Transfac motifs are dubious. V$BEN_02 motif has partial similarity to a shift-experiment sequence (PMID:14645227), which shows DNA-binding and evidence of transcriptional regulation by knockdown experiments


Description: GTF2I repeat domain containing 1 [Source:HGNC Symbol;Acc:HGNC:4661]
Entrez Summary The protein encoded by this gene contains five GTF2I-like repeats and each repeat possesses a potential helix-loop-helix (HLH) motif. It may have the ability to interact with other HLH-proteins and function as a transcription factor or as a positive transcriptional regulator under the control of Retinoblastoma protein. This gene plays a role in craniofacial and cognitive development and mutations have been associated with Williams-Beuren syndrome, a multisystem developmental disorder caused by deletion of multiple genes at 7q11.23. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2010]

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.

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
2a1, Lower confidence direct evidence
TF has conditional DNA-binding requirements
