This depends of course on your definition of signature motifs, taking this in a broad sense - many proteins that have multiple functional domains probably fit the bill, so you could search for "really huge proteins".
For example: FAS (human, not bacterial) - 2504 amino acids in a single chain (!) Eukaryotic type II topoisomerases GYRA/B LRP1-6 Membrane-spanning phosphatases ...

The dataset would need to consist of proteins that contain multiple signature motifs. I am having difficulty finding any with more than two signature motifs. I would be grateful if you can let me know of any proteins that have multiple (three or more) signature motifs. Thank you in advance.
