"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
1a1, Direct HQ evidence

The CXXC domain is found in a variety of chromatin-associated proteins. This domain binds to nonmethyl-CpG dinucleotides. The domain is characterised by two repeats [3], and shows a peculiar internal duplication in which the second unit is inserted into the first one [4]. Each of these units is characterised by four conserved cysteines, displaying a CXXCXXCX(n)C motif that chelate a Zn+2 ion. The DNA binding interface has been identified by NMR [3]. In eukaryotes, the CXXC domain is found in stramenopiles, plants and metazoans. Plants possess a mono-CXXC domain that is present in distinct chromatin proteins [4]. Structural comparisons show that the mono-CXXC is homologous to the structural-zinc binding domain of medium chain dehydrogenases [4].", "database": "PfamA", "aliStart": 960, "scoreName": "E-value", "accession": "PF02008.18", "start": 958, "score": 5.5999999999999996e-12, "identifier": "CXXC zinc finger domain", "type": "DBD", "aliEnd": 1005}}, {"startStyle": "straight", "end": 2691, "endStyle": "straight", "aliStart": 2586, "text": "SET", "colour": "#9999ff", "aliEnd": 2690, "start": 2586, "href": "http://pfam.xfam.org/family/PF00856.26", "type": "pfama", "display": "true", "metadata": {"end": 2691, "description": "SET domains are protein lysine methyltransferase enzymes.

The SET domain consists of two regions known as SET-N and SET-C. SET-C forms an unusual and conserved knot-like structure of probably functional importance.
