Another application is to retrieve all TFs that regulate a given (set of) gene(s). In the context of systems-biological studies, the TF-target gene relations documented in TRANSFAC were used to construct and analyze transcription regulatory networks. [14] [15] By far the most frequent use of TRANSFAC is the computational prediction of potential ...

The challenge of prediction tools is thus to filter harmless mutations from disease-causing ones. It is important to note that these tools are not designed to predict sources of complex diseases such as cancer. The latter usually do not have a monogenic causation but are caused by multiple gene defects that develop cumulatively into a disease.
Transcription factor naming issues were addressed through discussion of integration of transcription factor prediction pipelines, such as DBD or flyTF, which have been supplemented with manual curation versus solely manual curated implementations like TFcat.
Other transcription factors differentially regulate the expression of various genes by binding to enhancer regions of DNA adjacent to regulated genes. These transcription factors are critical to making sure that genes are expressed in the right cell at the right time and in the right amount, depending on the changing requirements of the organism.
Nine-amino-acid transactivation domain (9aaTAD) defines a domain common to a large superfamily of eukaryotic transcription factors represented by Gal4, Oaf1, Leu3, Rtg3, Pho4, Gln3, Gcn4 in yeast, and by p53, NFAT, NF-κB and VP16 in mammals. The definition largely overlaps with an "acidic" family definition. A 9aaTAD prediction tool is available.
Ab Initio gene prediction is an intrinsic method based on gene content and signal detection. Because of the inherent expense and difficulty in obtaining extrinsic evidence for many genes, it is also necessary to resort to ab initio gene finding, in which the genomic DNA sequence alone is systematically searched for certain tell-tale signs of protein-coding genes.
