Abstract
- It is shown here that in the yeast protein interaction network the global centrality measure (betweenness) depends on the protein evolutionary age (i.e., on historic contingency) more weakly than the local centrality measure (degree). This phenomenon is not observed in mutational duplication-and-divergence models. The network domains responsible for this difference deal with DNA/RNA information processing, regulation, and cell cycle. A selection vector can operate in these domains, which integrates the network activity and thus compensates for the process of mutational divergence. [ABSTRACT FROM AUTHOR]
