BIOBASE Training TRANSFAC® ExPlain™ Containing data on eukaryotic transcription factors, their experimentally-proven binding sites, and regulated genes ExPlain™ Combining promoter and pathway analysis to understand differential gene expression

Simplifies the vast biological literature space Focuses on peer-reviewed scientific literature Experimental results are extracted by highly trained scientific curators Content is updated quarterly

Provides easy access to experimental data Information extracted from the literature is organized using controlled vocabulary standards, therefore it is easily searchable Species specific, detailed curation is organized into focused reports Analysis tools provide opportunities to leverage known information for your research needs

TRANSFAC® and ExPlain™ advantages View how transcription factors are known to regulate target genes Perform prediction of transcription factor binding sites Model how transcription factors act together to affect gene expression patterns Understand the cause, not just the effect, of differential gene expression in response to drug treatment, disease state, environmental stimulus and more

More than 2,000,000 data points

Match™ – Matrix-based TF binding site search ttcttgaatgtaaacgtttaacaataaatcgcttgaat A 2 4 5 3 1 7 C 6 G T score s1 Match scans the submitted sequence with each matrix from the profile. If the matrix similarity score for a subsequence is greater than the selected cut-off, the subsequence is included as a putative binding site in the Match result.
