TF-CAT classification	TF Gene_Transcription Factor Binding tf co-factor binding_TF PPI_ PMIDS:9334314
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.	a
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
GO-Info
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	1a1, Direct HQ evidence
TF has conditional DNA-binding requirements
