PEPPER - Protein complex Expansion using Protein-Protein intERactions - pulls out all the stops when it comes to contriving a functional word, skipping words and using internal letters.
For the curious, PEPPER is available from the Cytoscape App Store and is:
“designed to identify protein complexes as densely connected subnetworks from seed lists of proteins derived from proteomic studies. Pepper identifies connected subgraph by using multi-objective optimization involving two functions: (i) the coverage, a solution must contain as many proteins from the seed as possible, (ii) the density, the proteins of a solution must be as connected as possible, using only interactions from a proteome-wide interaction network.”
Despite its use of “seed lists”, I don’t think there is a direct connection with peppers, so PEPPER is being classified as an ad hoc intranym.
I’m not sure if there’s a bigger version of the logo available but if you look carefully, you can see the little chilli peppers.
