Abstract(in English) | Protein networks perform a large variety of essential functions in the cells of living organisms. Here we analyze the degree distribution of kinds of domains network in H. Sapiens and A. Thaliana organisms. The results show that while (a) the number of domain types shared by k proteins exhibits a power-law distribution, (b) the number of proteins composed of k types of domains decays as an exponential distribution. These empirical findings encourage us to develop an evolutionary network model to explain the emergence of this mixing of (a) power-law and (b) exponential distributions. Our theoretical and computational results show that this network model requires (1) growth process and (2) copy mechanism. |
