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"	Yes

This 'helix-loop-helix' (HLH) domain mediates protein dimerization and has been found in the proteins listed below [PUBMED:1521738]. Most of these proteins have an extra basic region of about 15 amino acid residues that is adjacent to the HLH domain and specifically binds to DNA. They are refered as basic helix-loop-helix proteins (bHLH), and are classified in two groups: class A (ubiquitous) and class B (tissue-specific). Members of the bHLH family bind variations on the core sequence 'CANNTG', also refered to as the E-box motif. The homo- or heterodimerization mediated by the HLH domain is independent of, but necessary for DNA binding, as two basic regions are required for DNA binding activity. The HLH proteins lacking the basic domain (Emc, Id) function as negative regulators, since they form heterodimers, but fail to bind DNA.
