DOI: 10.1371/journal.pone.0113318

[…] a list of over-represented transcription factor binding sites together with occurrences of each site and a matrix similarity score. occurrences having the score of at least 0.8 were fed into matdefine (genomatix software package) to create a highly conserved matrix for each transcription factor binding site. the settings were as follows: tuple size – 8; no. of sequences containing tuple […]

PMID: 21177654
DOI: 10.1093/nar/gkq1301

[…] performed with a position-specific scoring matrix (pssm) built using 347 experimentally validated binding sites (). matrix generation and scan of sequences were done using the genomatix suite, with matdefine and matinspector programs (), respectively. significant overrepresentation of sbs in bidirectional promoters was evaluated using the khi2 test for two proportions, with alpha = 0.05 and 1 […]

DOI: 10.1074/jbc.M110.154732

[…] similar sequences were extracted from the top 1000 sequences with the highest signal rates in the chip-seq data using the matinspector search tool (). the final motifs were generated with the matdefine tool () using the frequency of the extracted sequences from matinspector., the duplex constructs for each small interfering rna (sirna) targeting hnf4α mrna, i.e. 4α-(i) and 4α-(ii), along […]

[…] and generated a dataset containing the promoters of the genes coding for the mrnas spotted on the chip. the hre matrix has been obtained from 69 experimental validated human hre sequences [] with matdefine tool (genomatix software gmbh). hre consensus elements [(g|c|a|t) (c|g|t|a) (g|c|a|t) (t|g|c|a) (a|g) (cgtg) (c|g|t|a) (g|c|a|t) (g|c|t|a) (c|g|t|a)] were searched in the promoter sequences […]
