Phylogeny, Functional Annotation, and Protein Interaction Network Analyses of the Xenopus tropicalis Basic Helix-Loop-Helix Transcription Factors

Figure 2

STRING mapping profiles of protein interaction network (PIN) representing bHLH transcription factor protein interactions. Panel (a) showed the main figure of PIN profile and connectivity of hub proteins and the others. The protein interacting gene products are marked in blue and green lines. There are totally 68 hub proteins identified and many hub proteins created a tight network or a functional module within their protein families. Panel (b) magnified the implication of different connective lines with different data sources in the main figure.
