Identification of the C. jejuni motility protein network. (a) The subset of high confidence interactions involving all proteins annotated  as having roles in motility. Only six small networks fall outside of the single large network. Protein colors are as follows: blue, putative chemotaxis proteins; red, putative methyl-accepting chemotaxis proteins (MCPs); green, putative flagellar/motility proteins; and yellow, proteins not annotated as motility-related. The box highlights CheA and its interactors, including Cj0643 (see text). Gene names can be read by zooming in. (b) A subsection of the motility network highlighting the proteins in the canonical chemotaxis signal transduction pathway (MCP, CheW, CheA, CheY, and FliM) and their interactors. Proteins are colored as in (a), above. To improve visibility of interactions comprising the chemotaxis backbone, nodes not previously identified as related to chemotaxis or motility (yellow) were removed if they connected to only one red, blue, or green node.
