Figure 3From: Metamotifs - a generative model for building families of nucleotide position weight matricesMetamotif inference from clustered TRANSFAC motifs. Examples of metamotifs inferred with the metamotif nested sampler algorithm from clustered motifs deposited in the TRANSFAC database [37]. Three metamotif sets (A,B,C) were estimated from input motif sets (D, E and F, respectively). A) Two largely similar patterns (metamotifs 1 and 2) are inferred that correspond to the muscle initiator like motifs, with one distinct pattern (metamotif 3) corresponding to the CATTCC-like motifs (members of the TEA family) also found from the cluster. B) shows that the metamotif nested sampler distinguishes a CAGATG-like (metamotif 1) and CAGCTG-like pattern (metamotif 2) from the motif cluster 3E, and separates an Sn (M00044)-like outlier from the two patterns as metamotif 3. C) Three metamotif patterns inferred from the motif set separate the TAACCCG-like (metamotif 1), TTACCCG (metamotif 2) and TAACCGTTT (metamotif 3) like patterns seen in the motif cluster. Notably metamotif3 contains a shorter CCG-like core instead of the CCCG found in the two other metamotifs.Back to article page
