Description: interferon regulatory factor 1 [Source:HGNC Symbol;Acc:HGNC:6116]
Entrez Summary The protein encoded by this gene is a transcriptional regulator and tumor suppressor, serving as an activator of genes involved in both innate and acquired immune responses. The encoded protein activates the transcription of genes involved in the body's response to viruses and bacteria, playing a role in cell proliferation, apoptosis, the immune response, and DNA damage response. This protein represses the transcription of several other genes. As a tumor suppressor, it both suppresses tumor cell growth and stimulates an immune response against tumor cells. Defects in this gene have been associated with gastric cancer, myelogenous leukemia, and lung cancer. [provided by RefSeq, Aug 2017]

"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

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
