Motifs: Using Databases & Creating Your Own

Searching Motif Databases

Background Information: Proteins having related functions may not show overall high homology yet may contain sequences of amino acid residues that are highly conserved. For background information on this see PROSITE at ExPASy. N.B. I recommend that you check your protein sequence with at least two different search engines. Alternatively, use a meta site such as MOTIF (GenomeNet, Institute for Chemical Research, Kyoto University, Japan) to simultaneously carry out Prosite, Blocks, ProDom, Prints and Pfam search

Discover Your Own Motifs:

After you have discovered similar sequences but the motif searching tools have failed to recognize your group of proteins you can use the following tools to create a list of potential motifs.


The MEME Suite

The MEME Suite - Motif-based sequence analysis tools (National Biomedical Computation Resource, U.S.A.). N.B. After doing a BLASTP search create a FASTA-formated document containing three or four of the most homologous proteins (training set) and submit to MEME (Multiple Em for Motif Elicitation) or GLAM2 (Gapped Local Alignments of Motifs). In the case of MEME I usually specify 5 as the "Maximum number of motifs" to find. You will receive a message by E-mail entitled "MEME Submission Information (job app.......), " verifies that the NBCR received and is processing your request. If you click on the hyperlink "You can view your job results at: http://meme..." you will see:

Meme_Mast

The "MAST output as HTML" provides the motifs, a motif alignment graphic and the alignment of the motifs with the individual sequences in the training set. The "MEME output as HTML" file contains a detailed analysis of each of the motifs plus their Sequence Logos.

At the top of the life is a buttom labelled "Search sequence databases for the best combined matches with these motifs using MAST." This will take you to the MAST (Motif Alignment and Search Tool) submission form. Click on the NCBI nonredundant protein database. You will receive an E-mail entitled "MAST Submission Information (job app ...)."

Use great caution before printing the second set of data can be >20 pages (Reference: Bailey, T.L. et al. 2009. Nucl. Acids Res. 37(Web Server issue): W202-W208). The Meme Suite can also be found here.
