  • Title: Comparative evolutionary analysis of cell cycle proteins networks in fission and budding yeast.
    Author: Singh PK, Shakya M.
    Journal: Cell Biochem Biophys; 2014 Nov; 70(2):1167-75. PubMed ID: 24906232.
    Abstract:
    Fission yeast and budding yeast are the two distantly related species with common ancestors. Various studies have shown significant differences in metabolic networks and regulatory networks. Cell cycle regulatory proteins in both species have differences in structural as well as in functional organization. Orthologous proteins in cell cycle regulatory protein networks seem to play contemporary role in both species during the evolution but little is known about non-orthologous proteins. Here, we used system biology approach to compare topological parameters of orthologous and non-orthologous proteins to find their contributions during the evolution to make an efficient cell cycle regulation. Observed results have shown a significant role of non-orthologous proteins in fission yeast in maintaining the efficiency of cell cycle regulation with less number of proteins as compared to budding yeast.
