Conclusion

Assessment Binding Mode Motif Status Notes Comments
Inferred motif 1 Monomer or homomultimer In vivo/Misc source Has a putative AT-hook Binds to NFKB-like consensus sequence to repress transcription (PMID: 21189157). PWMs for HIVEP1 and 2 in Transfac and Hocomoco are also NFKB-like.

Description

Description: human immunodeficiency virus type I enhancer binding protein 3 [Source:HGNC Symbol;Acc:HGNC:13561]
Entrez Summary This gene encodes a member of the human immunodeficiency virus type 1 enhancer-binding protein family. Members of this protein family contain multiple zinc finger and acid-rich (ZAS) domains and serine-threonine rich regions. This protein acts as a transcription factor and is able to regulate nuclear factor kappaB-mediated transcription by binding the kappaB motif in target genes. This protein also binds the recombination signal sequence that flanks the V, D, and J regions of immunoglobulin and T-cell receptors. Alternate splicing results in both coding and non-coding transcript variants. [provided by RefSeq, Sep 2011]

Source Annotation
TF-CAT classification No
PMIDS:
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
2a2, orthologous lower confidence evidence
TF has conditional DNA-binding requirements
