Assessment Binding Mode Motif Status Notes Comments
Likely to be sequence specific TF 1 Monomer or homomultimer No motif (PMID: 18326499) shows through SELEX and EMSA that this family binds DNA specifically.


Description: GTF2I repeat domain containing 2B [Source:HGNC Symbol;Acc:HGNC:33125]
Entrez Summary This gene encodes a glycosylated phosphoprotein with a leucine zipper motif, two helix-loop-helix motifs (I repeats) that are similar to domains found in the TFII-I family of transcription factors, one CHARLIE8 transposable element-like sequence, and a BED zinc finger. This gene lies within a region that is deleted in Williams-Beuren syndrome. Alternatively spliced variants which encode different protein isoforms have been described; however, not all variants have been fully characterized. [provided by RefSeq, Jul 2008]

Source Annotation
TF-CAT classification Indeterminate - There is no evidence for or against this genes role as a TF___
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? No
Has GO:0003700 "transcription factor activity, sequence-specific DNA binding" Yes
GO-Info GO:0000981
sequence-specific DNA binding RNA polymerase II transcription factor activity
IBA - GO_REF:0000033
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
